TECHNICAL FIELD
The present invention relates to an olefin derived copolymer and a thermoplastic resin composition. Furthermore in detail, the present invention relates to an olefin derived copolymer that may provide a thermoplastic resin composition with outstanding flexibility, transparency, resistance to whitening, scratch resistance, and tensile elongation characteristics, and excellent balance of flexibility, heat resistance, and weather resistance, and outstanding surface character stability and relates to a thermoplastic resin composition therewith.
BACKGROUND TECHNOLOGY
Soft vinyl chloride resin is a material that has excellent performances, such as outstanding flexibility, heat resistance, scratch resistance, and transparency, and is widely used in many fields. However, in recent years materials responsible for environmental problem comes to be required, and a demand for substitution to non-soft vinyl chloride material is increasing in use where soft vinyl chloride has been conventionally used. In such a background, as a soft material consisting only of olefin component, a resin composition comprising ethylene-α-olefin copolymer and crystalline polypropylene resin is known as thermoplastic resin compositions (JP,7-102126,A etc.) excellent in flexibility, transparency, mechanical strength, resistance to whitening, and cold resistance. However, a problem of stickiness of surface originated in ethylene-α-olefin copolymer remains as is described in JP,8-301927,A, and the material is not provided in practical use.
On the other hand, as a trial improving these stickiness, although a method of cross-linking with electron beam or peroxide in copolymer comprising ethylene-α-olefin etc. is also proposed (JP,8-301927,A, JP,9-104720,A), still sufficient result is not given. On the other hand, a tacky adhesion sheet or film comprises base material films, such as vinyl chloride resin, polyethylene, and polypropylene etc. and pressure sensitive adhesive layers with acrylics derived or rubber derived main components. These tacky adhesion sheets or films are often used as surface protection film and a tape for fixation and union at the time of packaging and packing in order to prevent crack and soils during storage or transportation of materials, such as construction materials, stainless steel, aluminum board, home electronics, precision instrument, and car, or in order to prevent getting damaged in case of secondary processings, such as bend processing and press processing. However, in recent years although a tacky adhesion film made of vinyl chloride resin group material is excellent in performances, such as flexibility, heat resistance, scratch resistance, and transparency, a conversion demand into non-chlorine derived material is increasing in material demands for environmental problem. On the other hand, although a tacky adhesion film made of polyethylene and polypropylene group material is also conventionally used in some fields as a non-chlorine derived material, a sufficient result is not given, for example in the field where advanced flexibility, such as close contact to an objects to be covered and ductility at the time of processing, is required. And although a trial in which ethylene-α-olefin copolymer with excellent flexibility is added to polyethylene or polypropylene is also carried out for the purpose of providing flexibility in response to this situation, a problem is induced that heat resistance is greatly spoiled or surface stickiness arises, if excessive amount of this ethylene-α-olefin copolymer is added in order to raise flexibility. Moreover, a material, as non-chlorine derived material using olefin derived polymer, in which styrene derived block copolymer is blended into polypropylene is inadequate in flexibility compared with vinyl chloride resin. And since styrene block unit is contained in large quantities, depending on used condition, weather resistance at the time of outdoor exposure and especially ultraviolet radiation stability are not necessarily enough to give a possible problem of decrease in physical properties in use out in the fields.
SUMMARY OF THE INVENTION
In this situation, as a result of wholehearted investigation performed by the present inventors in search of a composition that has outstanding flexibility, transparency, resistance to whitening, scratch resistance, and tensile elongation characteristics, and also has an outstanding balance of flexibility, heat resistance, and weatherproof when blended with polyolefin resin, and at the same time of a new modified material that can prevent a stickiness phenomenon, as in weathering test of car interior, after high temperature heat resistance examination, it was found out that the above-mentioned subject is solved by using a new olefin derived copolymer with certain specific physical properties. Moreover, by using a base material sheet or film containing a thermoplastic resin composition of the present invention, it was found out that the above-mentioned subject is solved to complete the present invention.
A subject solved by the present invention is to provide an olefin derived copolymer that consists only of olefin without chlorine and that gives a thermoplastic resin composition having outstanding flexibility, transparency, resistance to whitening, scratch resistance, and tensile elongation characteristics, and an excellent balance in flexibility, heat resistance, and weather resistance, and that does not generate decrease in surface character after heating promoted examination, and to provide a thermoplastic resin composition using the olefin derived copolymer.
Namely, the present invention relates to an olefin derived copolymer and a thermoplastic resin composition using the olefin derived copolymer satisfying the following (1) and (2):

    
    
        (1) tensile strength at break measured based on JIS K6251 is 2.0 or less MPa; and
        (2) tensile elongation at break EB (%) of a resin composition obtained satisfies the following relational expression (expression 1) and (expression 2), when blended with a polypropylene derived resin that has 20 degree C. xylene solluble component of not more than 20 wt %.

R[3/5]−R[2/6]≧0.15  (expression 1)

S[2/6]≧−800  (expression 2)

        (R[3/5] and R[2/6] are obtained by the following methods:
        a curve is obtained by plotting tensile elongation at break EB (%) (based on JIS K6251) of resin composition taken as vertical axis, and weight part rate Pa of a content of an olefin derived copolymer contained in a resin composition taken as horizontal axis; a multiple regression curve in section regions of Pa=0.30-0.50 and Pa=0.20-0.60 (Pa represents content weight percentage of an olefin derived copolymer contained in a resin composition) of a multiple regression expression obtained by quintic multiple regression of the curve is obtained;
        R[3/5] and R[2/6] are defined as multiple correlation coefficients of a primary straight line obtained by approximating of the multiple regression curve by method of least squares. S[2/6] represents a gradient of a primary straight line (expression) obtained by approximating the above-mentioned multiple regression curve by a method of least squares insection region of Pa=0.20-0.60. In addition, in the above-mentioned multiple regression expression, it is indispensable that data at least seven points Pa=0.00, 0.20, 0.30, 0.40, 0.50, 0.60 and 0.70 are contained. Furthermore, when data at points of number beyond above case are contained, it is indispensable that total Pa values exist at 0.10 or less of fixed interval mutually.

In addition, 20-degree C. xylene soluble component of a polypropylene derived resin is a value according to the following method and conditions. That is, polypropylene derived resin about 200 mg is weighed, and it is mixed with xylene 10 ml, and in boiling xylene, dissolved for 50 minutes. After predetermined period, cooled for 20 minutes at room temperature, the polypropylene derived resin is crystallized in 0-degree C. iced water. Then, the solution is kept in a 20-degree C. homothermal water bath for 1 hour. Subsequently, a xylene soluble component and a xylene non-soluble component are separated by filtering, and the xylene non-soluble component is dried until it reaches constant weight in a vacuum dryer. After the xylene non-soluble component is weighed, and a weight difference from the original sample was obtained as a weight of xylene soluble component. Xylene soluble component (wt %) is obtained as a percentage of a xylene soluble component weight to an original sample weight.
Moreover, it is preferable that a crystallization temperature Tc (degree C.) and crystallization calorie ΔH (mj/mg) measured using a differential scanning calorimeter (DSC) of a polypropylene derived resin (X) with 20-degree C. xylene soluble component of not more than 20 wt % may satisfy the following relationship.

more preferably −8≦[ΔH−(Tc×1.4)−62]≦8,

still preferably −6≦[ΔH−(Tc×1.4)−62]≦6.

If a polypropylene derived resin (X) with 20-degree C. xylene soluble component of not more than 20 wt % goes out of this range, a specific olefin derived copolymer may not be judged correctly that can provide a thermoplastic resin composition having outstanding flexibility, transparency, resistance to whitening, scratch resistance, elongation and surface stability characteristics.
Next, a polypropylene derived resin (X) with 20-degree C. xylene soluble component of not more than 20 wt % is a crystalline polypropylene that mainly has an isotactic or syndiotactic sequence structure, and preferably homogenous type and random type containing comonomer, more preferably random type polypropylene derived resin containing comonomer. In addition, in manufacturing the polypropylene derived resin, vapor phase polymerization method, bulk polymerization method, and solvent polymerization method may be adopted. And there is especially no limitation for a number average molecular weight of polymer, and is preferably adjusted to 10000-1000000.
As a method of manufacturing polypropylene derived resin (X) which has 20-degree C. xylene soluble component not more than 20 wt %, generally, following methods may be mentioned: a method wherein, homopolymerized propylene is obtained using Ziegler-Natta type catalyst in which so-called solid transition metal components containing titanium, and organic metal components are used in combination or a metallocene catalyst that comprises transition metal compounds of the 4th to 6th group in periodic table with at least one cyclopentadienyl frame and co-catalyst components by slurry polymerization, vapor phase polymerization, and bulk polymerization; and a method wherein, copolymerized propylene is obtained by copolymerising propylene and one or more kinds of olefins chosen from olefin with 2-12 carbons other than propylene. In addition, it is also possible to use commercially available corresponding materials.
Next, in the light of flexibility of blended materials with polyolefin resins it is preferable that olefin derived copolymers of the present invention satisfy the following characteristics in addition to the above-mentioned characteristics. That is, flexural modulus (Ua (MPa)) of a thermoplastic resin compositions obtained as blended materials with homogeneous polypropylene resin measured based on JIS K7203 preferably satisfies a relationship of the following expression,

Ua≦1.5×Sa×(Ta/100)3.3,

still more preferably Ua≦1.3×Sa×(Ta/100)3.3,

especially preferably Ua≦1.2×Sa×(Ta/100)3.3.

If Ua goes out of the above-mentioned range, flexibility, transparency, resistance to whitening, and scratch resistance of the thermoplastic resin compositions obtained and a molded body containing the thermoplastic resin compositions obtained may be decreased. In addition, in the above-mentioned expression, Sa represents flexural modulus (MPa) of the homogeneous polypropylene resins used for blending, measured based on JIS K7203, and Ta represents added weight part (wt %) of the homogeneous polypropylene resins in the thermoplastic resin compositions.

Moreover, if the intrinsic viscosity is too high, flexibility and transparency of a molded body containing the thermoplastic resin compositions obtained and the thermoplastic resin compositions obtained may be decreased.
Measurement of intrinsic viscosity [η] is performed using an Ubbelohde viscometer in 135-degree C. tetralin. Sample 300 mg is dissolved in 100 ml tetralin, and 3 mg/ml solution was prepared. Furthermore, the solution concerned is diluted into 1/2, 1/3, and 1/5, and a viscosity of each diluted solution is measured in 135 degrees C. (±0.1 degrees C.) oil thermostat.

A molecular weight distribution (Mw/Mn) of an olefin derived copolymers of the present invention, measured by gel permeation chromatography (GPC) is preferably five or less, more preferably four or less, and still more preferably three or less. When a molecular weight distribution is too wide, flexibility of a molded body containing thermoplastic resin compositions obtained and a thermoplastic resin compositions obtained may be inferior. And moreover, that a molecular weight distribution of a polymer obtained by one-bath polymerization is large generally means a wide intermolecular composition distribution. In such a case, decrease in surface character with the passage of time of a thermoplastic resin compositions obtained and a molded body containing the thermoplastic resin compositions may be observed.
As for molecular weight distribution, measurement is performed by gel permeation chromatography (GPC) method (for example, 150 C/GPC equipment, apparatus made by Waters Co., Ltd.) Measurement conditions are as follows; elution temperature: 140 degrees C.; column used: for example, Sodex Packed Column A-80M (by Showa Denko K.K.); molecular weight standard substance: polystyrene (for example, made by TOSOH CORP., molecular weight 68-8400000). From obtained polystyrene converted weight average molecular weight (Mw) and number average molecular weight (Mn), ratio (Mw/Mn) is calculated and this is defined as a molecular weight distribution. A measuring sample of about five mg polymer is dissolved in five ml o-dichlorobenzene, and solution with a concentration of about one mg/ml is obtained. Obtained sample solution 400 micro litter is injected, detection is performed using a refractive index detecting element at elution solvent flow velocity of 1.0 ml/min.
Next, when measurement is performed based on JIS K7122 using differential scanning calorimeter (DSC), an olefin derived copolymer of the present invention preferably has neither a peak of one or more J/g based on fusion of crystal nor a peak of one or more J/g based on crystallization.

Components (i) used for thermoplastic resin compositions of the present invention are thermoplastic resins. (i) may be widely selected from various well-known thermoplastic resins, for example, polyethylene derived resins, such as high-density polyethylene and middle-density polyethylene, low-density polyethylene,-and linear low-density polyethylene (LLDPE); polypropylene derived resins; polybutene derived resins: poly-4-methyl-pentene-1 derived resins; polystyrene derived resins; polyester derived resins; polyamide derived resins; poly phenyleneether derived resins; polyphenylene oxide-resins; polyacetal derived resins; polycarbonate derived resins, etc. may be mentioned.

In addition, as a polymerization method of the polypropylene derived resins, a vapor phase polymerization method, a bulk polymerization method, a solvent polymerization method, and a multi-stage polymerization in which the above-mentioned methods are combined arbitrarily are employable. Moreover, there is especially no limitation in a number average molecular weight of polymer, and it is preferably adjusted to 10000-1000000.

A melting point is preferably in a range of 80 degrees C.-176 degrees C., and, an amount of crystal melting calorie is preferably is in a range of 30 J/g-120 J/g. More preferably, a melting point is in a range of 120 degrees C.-176 degrees C., and an amount of crystal melting calorie in a range of 60 J/g-120 J/g. If a melting point is too low or an amount of heat of fusion is too small, heat resistance of thermoplastic resin compositions and a molded body containing thermoplastic resin compositions obtained may be decreased.
Following methods are used as methods of manufacturing (i-4) polypropylene derived resins. Generally as catalysts, so-called Ziegler-Natta type catalysts in which transition metal components in a shape of a solid containing titanium and organic metal components are combined, or metallocene catalysts that consist of transition metal compounds of the 4th group—the 6th group of periodic table with at least one cyclopentadienyl frame and co-catalyst components are used. As polymerization methods, slurry polymerization, vapor phase polymerization, bulk polymerization, solution polymerization, etc. are used, or methods in which the above-mentioned methods are combined are used in one-step or multi-step to obtain homopolymerized polypropylenes. Moreover, copolymerized polypropylenes may be obtained by copolymerizing propylene with one or more olefins selected from olefins having 2-12 carbons other than propylene in one-step or multi-step using the above-mentioned methods. In addition, it is also possible to use commercially available materials.
In thermoplastic resin compositions and a molded body containing thermoplastic resin compositions of the present invention, when flexibility, transparency, resistance to whitening, scratch resistance, and excellent performance balance are required, it is preferable that (i) are polypropylene derived resins (i-6) in which 15 or more to 205 or less of methylene carbons in two or more chains are contained in 1000 carbon chains as main chain. More preferably, 25 or more to 155 or less of methylene carbons in two or more chains are contained in 1000 carbon chains as main chain, and still more preferably 35 or more to 105 or less. If (i-6) goes out of the range, flexibility, transparency, resistance to whitening, and scratch resistance of thermoplastic resin compositions and a molded body containing thermoplastic resin compositions obtained may be decreased. As methods of having a predetermined number of methylene carbons of two or more chains contained into (i-6), a method of copolymerizing ethylene to propylene, and a method of forming tail-to-tail bonds of propylene may be mentioned. Content of methylene carbons of two or more chains contained in 1000 carbon chains of (i-6) as main chain can be measured using 13C-NMR, IR, etc. The analysis method of 13C-NMR and IR is indicated in New Edition Macromolecule Analysis Handbook 1.2.3 (1995).
When performance excellent in shock resistance and resistance to whitening is required for a molded body containing thermoplastic resin compositions and thermoplastic resin compositions of the present invention, it is preferable that (i) are polypropylene derived resin compositions (i-7) obtained by having ethylene and propylene copolymerized in two or more steps. In detail, (i-7) represents the following compositions: in a first step, a photopolymer of propylene, or ethylene propylene copolymer having 5.0 or less weight % of ethylene content is obtained, and in a second step or after, ethylene propylene copolymer having 7-85 weight % of ethylene content is obtained, and at the same time, a weight ratio of a polymer obtained in a first step to a polymer obtained in a second step or after is 30/70-90/10. (A propylene homopolymer or ethylene propylene copolymer obtained in a polymerization of a first step may be denoted as “copolymer-1” hereinafter. And ethylene propylene copolymer obtained in a copolymerization in a second step or after may be denoted as “copolymer-2”.)
Ethylene content of the copolymer-1 is preferably 5.0 or less weight %. If ethylene content exceeds 5.0 weight %, heat resistance of thermoplastic resin compositions and a molded body containing thermoplastic resin compositions obtained using the polypropylene derived resin compositions may be decreased.
Eethylene content of the copolymer-2 is preferably 7-85 weight %. The resistance to whitening of thermoplastic resin compositions obtained using the polypropylene derived resin compositions may be decreased when ethylene content is too small. Alternatively when ethylene content is excessive, shock resistance of thermoplastic resin compositions and a molded body containing thermoplastic resin compositions obtained using the polypropylene derived resin compositions may be decreased.
A weight ratio of the copolymer-1 and the copolymer-2 is 30/70-90/10. When a content of the copolymer-1 is too little (the copolymer-2 is excessive), thermoplastic resin compositions and, and a molded body containing thermoplastic resin compositions obtained using the polypropylene derived resin compositions cannot obtain sufficient resistance to whitening. On the other hand, when the copolymer-1 is excessive (content of the copolymer-2 is too little), inadequate shock resistance may be obtained in the thermoplastic resin compositions and the molded body containing thermoplastic resin compositions that are obtained using the polypropylene derived resin compositions.
In addition small quantity, for example, about one to five weight %, of α-olefins other than propylene and ethylene (for example, butene-1, hexene-1, octene-1, etc.) may be contained in the copolymer-1 and copolymer-2.
Common name of the above-mentioned polypropylene derived resins is sometimes “block polypropylene” or “high impact polypropylene”, and commercially available materials may be used.
When performance excellent in transparency, elongation, flexibility, and workability is required for thermoplastic resin compositions, and a molded body containing thermoplastic resin compositions of the present invention, it is preferable that (i) is propylene-ethylene copolymers (i-8) that have JIS A hardness of 70-97 measured based on JIS K6301, and have modulus of elasticity in bending measured based on JIS K7203 of 50-500 MPa.
JIS A hardness of (i-8) measured based on JIS K6301 is preferably 70-97, more preferably 75-97. When the hardness is too small, heat resistance of thermoplastic resin compositions obtained and a molded body containing thermoplastic resin compositions may be decreased. On the other hand, when the hardness is excessive, flexibility of thermoplastic resin compositions obtained and a molded body containing thermoplastic resin compositions may be decreased.
Modulus of elasticity in bending of (i-8) measured based on JIS K7203 is preferably 50-500 MPa, and more preferably is 55-450 MPa.

From a viewpoint of transparency of a molded body using olefin derived copolymer compositions obtained, resins with aliphatic and/or cycloaliphatic structure in these resins are more preferable. Here, as especially preferable resins giving tackiness that have aliphatic and/or cycloaliphatic structure: in rosin derived resins partially and fully hydrogenated rosin and those derivatives; in poly terpene derived resins, homopolymers or copolymers of cyclic terpenes; in synthetic petroleum resins, hydrogenated copolymer of aliphatic derived petroleum resin, cycloaliphatic derived petroleum resin, aliphatic-cycloaliphatic copolymerized resins, naphtha cracked oils, and various terpene may be mentioned. These resin components are used independently, or in combination of mixture of two or more kinds. In addition, corresponding commercial materials may be used as resin components.
Thermoplastic resin compositions of the present invention may be used as multilayered materials of two or more layers that have at least one layer consisting of thermoplastic resin compositions of the present invention. Materials of layers in the laminated layers constituting each layer may be the same mutually or may be different from each other. As materials constituting each layer, it is possible to be selected from well-known components of thermoplastic resins, rubbers, and others besides thermoplastic resin compositions of the present invention. As thermoplastic resins among these materials, resins selected from a following group may be used: various ethylene derived resins, various polypropylene derived resins various polybutene derived resins, various polymethylpentene derived resins, polystyrene derived resins; copolymer resins of ethylene and acrylic acid derived monomers; copolymer resins of ethylene and vinyl acetate derived monomers; copolymer resins of ethylene and methacrylic acid derived monomers; acrylate resins, polyester derived resins, polycarbonate derived resins, nylon derived resins, polyvinylalcohol derived resins.

In addition, adhesives to provide adhesive property may be inserted to between layers of multilayered materials if needed.
As methods of obtaining thermoplastic resin compositions of the present invention, each component explained above may be kneaded using for example, usual kneading equipment, rubber mills, Brabender mixers, Banbury mixers, pressurized kneaders, ruders, biaxial extruders, etc. As kneading equipment, both sealed system and open system may be used, but equipments by sealed system type that may be substituted by inert gas are preferable. Kneading temperature is a temperature at which all the mixed constitution components are melted, and is usually 160-250 degrees C., and is preferably 180-240 degrees C. Although it is not generally discussed because of dependency on kinds of mixed constituting components, quantity, and kind of kneading equipments, kneading time is usually about 3-10 minutes, when using kneading equipments, such as pressurized kneader and Banbury mixers. In addition, in kneading process, each constitutiing components may be collectively kneaded, and a multi-stage division kneading method in which after some constituting components are kneaded at a first, remaining constituting components are added and kneading is continued is also employable.
It is preferable that thermoplastic resin compositions of the present invention have pellet-like shape in consideration of transfer or transportation. Although known technology may be mentioned as methods of pelletizing of thermoplastic resin compositions, and for example, after uniformly molten, (i) thermoplastic resins and (ii) olefin derived copolymers are extruded by extruder, pellets in a shape of a globular, acylinder, and a lens are obtained by hot cutting or strand cutting. In this case, cutting may be carried out under any condition of air currents, underwater, in air, etc. Strands with dual structure, in which (i) thermoplastic resins as outer layer and (ii) olefin derived copolymers as inner layer are configured, may be obtained, and thus pellets that contain resins with low mutual adhesiveness may be supplied effectively, using equipments with system that can configure two-layered strands (inner layer and outer layer), with different polymers. And, after (i) thermoplastic resins and the (ii) olefin derived copolymers are molten and mixed uniformly, the mixture molded to obtain sheets with rolls etc. may be pelltized into cubic shape by sheet pelletizing machine. Pellets preferably have a length of longest portion of 3 cm or less in size. In the case of pellets with size exceeding this size, measurement error may become larger.
Pellets comprising thermoplastic resin compositions of the present invention may be preferably powdered on their surface with one kind or more of materials, such as calcium carbonate, barium sulfate, silica, talc, stearic acid, and poly olefin powder in the light of inhibition of pellet-bridging phenomenon caused by coagulation. A mount of powdering may be decided based on a size and a form of pellets, and it is preferably 0.05-3 weight parts based on an amount of pellets of thermoplastic resin compositions. Effect of stopping coagulation may be poor if added amount is too small, and if too much, decrease in physical properties and manufacturing cost rise may be caused.
Thermoplastic resin compositions of the present invention are primarily processed into various molding objects, such as pipe and joint, film, sheet, hose, inner tube, etc. using well-known methods, such as extrusion molding, variant extrusion molding, multi-color extrusion molding, covering (with core) extrusion molding, injection molding, compression molding, foamed molding, hollow molding, powder molding, calender molding, kneading processing, and inflation. For example, as an example of powder molding method, the slash molding method, the flow dipping method, electrostatic coating method, powder thermal spraying method, the powder rotational molding method, etc. are mentioned. And, as for molded bodies that consist of thermoplastic resin compositions of the present invention, well-known surface treatment, such as paint and vacuum evaporation, can be performed. Moreover, the above-mentioned primary products may further be processed to obtain commercial products by processing, such as bending, cutting, cut forming, die cutting, die drawing, sculpture, press processing, hot stamping, high-frequency fabricating, ultrasonic processing, lamination, sewing/rolled seaming/hand-knit, vacuum forming, pneumatic molding, adhesion, welding, hair transplantation, lining processing, slit processing, and printing.
Although base material films or sheets of the present invention may be transparent and colorless, coloring or printing may be given to be used.
Although especially manufacturing process of base material sheets or films of the present invention is not limited, for example, after each component is kneaded with dry blend or usual kneading equipment, for example, rubber mill, Brabender mixer, Banbury mixer, pressurized kneader, ruder, biaxial extruder, etc. the material may be processed to obtain laminated films and sheets by inflation method, extruding method by T type dice, uniaxial drawing method, biaxial drawing method, calender roll, etc. Although thickness of films obtained is not especially limited, it is preferably 0.02-2 mm, and more preferably about 0.03-0.2 mm.
Moreover, pressure sensitive adhesive layer may be prepared on at least one face of base material films of the present invention, or sheets to obtain tacky adhesion sheets or films may be provided. This pressure sensitive adhesive is not especially limited, and for example, rubber derived pressure sensitive adhesives, such as natural rubbers, ethylene-α-olefin copolymers, atactic polypropylenes, and propylene-α-olefin copolymers, ethylene-vinyl acetate copolymers, polyamides, polyesters, polycarbonates, poly vinyl ethers, polyvinyl alcohol, polyurethanes, styrene derived block copolymers, polyisobutylene-butyl rubber derivatives, and poly isoprene derivatives; acrylic derived pressure sensitive adhesives, such as graft polymer obtained by polymerization of the acrylics derived monomers, and copolymers with 2-ethyl hexyl acrylate and butyl acrylate as main monomer; silicone derived pressure sensitive adhesives etc. may be used as pressure sensitive adhesives in a form of solvent type, non-solvent type, emulsion type, water-soluble type, etc. Thickness of pressure sensitive adhesives usually has about 0.001-0.2 mm preferably. Moreover, softener, optical stabilizers (UV absorbent, quencher, etc.), antioxidant, anticorrosive, colorant, filler, age resistor, cross-linking agent, etc. may be added. Pressure sensitive adhesive may be coated on base materials by coating machine, and pressure sensitive adhesive layers are formed. In the light of environmental problems, working environment, etc. in these days, pressure sensitive adhesive layers are preferably prepared using a hot-melt coating method on films and sheets of base material. Moreover, in this case, base materials and pressure sensitive adhesive layers may be processed by technologies, such as co-extrusion method and the extrusion coating method (it is also called the extrusion laminating method), using inflation film manufacturing equipment, T die film manufacturing equipment, etc.
Furthermore, when using tacky adhesion sheets or films especially in rolls, it is preferable to reduce an affinity of tacky adhesion sheets or films to opposite side of themselves in the light of what is called releasing-out property, i.e., self-releasing property. For this reason, release coated papers may be inserted or releasing agents may be coated to a face opposite to a side in which pressure sensitive adhesive layer is given on base materials of tacky adhesion sheets or films.


EXAMPLE
Although the following examples describe the present invention still more concretely, these examples are for illustration and do not limit the present invention. [1] Synthesis of Olefin Derived Copolymer
Example 1
Copolymerization of ethylene, propylene, 1-butene, and 5-ethylidene-2-norbornene (ENB) was continuously performed using polymerization apparatus made of SUS of 100 L equipped with agitating blades. That is, hexane was continuously supplied as a polymerization solvent from a lower part of polymerization apparatus at the rate of 83 L/hour, and following raw materials were simultaneously supplied at each velocity continuously respectively; ethylene: 2.0 kg/hour; propylene: 8.3 kg/hour: 1-butene: 12.7 kg/hour; and 5-ethylidene-2-norbornene (ENB): 6.3 kg/hour. On the other hand, from upper part of the polymerization apparatus, polymerization liquid was continuously extracted so that the polymerization liquid in the polymerization apparatus might be kept a level of 100 L. As catalysts, dimethyl silyl(tetramethyl cyclopentadienyl)(3-tert-butyl-5-methyl-2-phenoxy)titanium dichloride, triphenylmethyl tetrakis(pentafluoro phenyl)borate, triisobutyl aluminum (henceforth referred to as TIBA) were continuously supplied into the polymerization apparatus at rates of 0.092 g/hour, 2.755 g/hour, and 5.251 g/hour respectively from the lower part of the polymerization apparatus. Moreover, molecular weight regulation was performed by hydrogen. Copolymerization reaction was performed at 50 degrees C. while circulating cooling water in a Jacket attached in exterior of the polymerization apparatus. A small amount of ethanol was added into a polymerization liquid extracted from the polymerization apparatus, and polymerization reaction was stopped. After monomer was stripped off and washed with water, solvent was removed off by steaming in a large amount of water, and thus copolymer was taken out. Copolymer was dried at 80 degrees C. day and night under reduced pressure. Thus ethylene/propylene/1-butene/5-ethylidene-2-norbornene copolymerization was performed at a rate of 2.39 kg/hour by the above operation.
Comparative Examples 1 and 2
In Example 1, except that the amount of monomer added and amount of catalyst added as shown in Table 1 were used, the same method was followed fundamentally and copolymer was obtained. Detailed result is summarized in Table 1.

[2] Analysis of Olefin Derived Copolymer
(1) IR Measurement
Copolymer obtained by Example 1 and Comparative examples 1 and 2 were analyzed by IR measurement. Methylene rocking vibration of ethylene at 720 cm−1, methyl group rocking vibration originated from methyl branch in propylene at 1154 cm−1, and methyl group rocking vibration originated from ethyl branch in 1-butene at 770 cm−1 were observed. This shows that copolymerization of each monomer component was carried out.
(2) Intrinsic Viscosity [η]
Measurement of intrinsic viscosity was performed in 135-degree C. tetralin using Ubbelohde viscometer. Sample 300 mg was dissolved in tetralin 100 ml, and 3 mg/ml of solution was prepared. Furthermore, the solution concerned was diluted into concentration of 1/2, 1/3, and 1/5, and each diluted solution was measured in oil thermostat bath at 135 degrees C. (±0.1 degrees C.). For each concentration, measurement was repeated 3 times and acquired value was averaged.
(3) Molecular Weight-distribution Measurement
Molecular weight distribution was measured by gel permeation chromatography (GPC) method (product made by Waters, 150 C/GPC equipment). Following condition was used; elution temperature: 140 degrees C., Used column: Sodex Packed Column A-80M by Showa Denko K.K., molecular weight standard substance: polystyrene (made by TOSOH CORP. molecular weight 68-8400000). Weight average molecular weight converted into polystyrene is defined as (Mw) and number average molecular weight as (Mn), and this ratio (Mw/Mn) is defined as molecular weight distribution. About 5 mg of measurement sample polymer was dissolved in o-dichlorobenzene 5 ml to obtain a solution with a concentration of about 1 mg/ml. Obtained sample solution 400 μl was injected. Elution solvent flow velocities were 1.0 ml/min, and detection was carried out by a refractive index detecting element.
(4) Differential Scanning Calorimeter (DSC) Measurement
Measurement was performed at the rate of 10 degrees C./min in both of temperature rising and constant process using a differential scanning calorimeter (DSC 220C by SEIKO Electronic Ind., Co.)
(5) Measurement of 5-ethylidene-2-norbornene (ENB) Content
Olefin derived copolymer was molded by heat pressing into a film shape of thickness of 0.5 mm. Subsequently, using infrared spectrometer, peak transmittancy (wave number 1650 cm−1) originated from 5-ethylidene-2-norbornene origin was obtained, and 5-ethylidene-2-norbornene content in olefin derived copolymer was calculated.

(Expression 5) was processed by linear regression in an area of Pa=0.20-0.60, and an area of Pa=0.30-0.50 using method of least squares, and, as a result, multiple correlation coefficients R[2/6] and R[3/5], gradient S[2/6], and gradient S[3/5] were obtained. In addition, in linear regression, as Pa, in section of Pa=0.20-0.60, relationship of 41 points that were obtained by substituting numerical values with 0.01 units containing 0.20 and 0.60 for (eq5) was used, and in section of Pa=0.30-0.50, relationship of 21 points that were obtained by substituting numerical value of 0.01 units containing 0.30 and 0.50 for (expression 5) were used.
Multiple correlation coefficient R[2/6], and R[3/5] gave the following values, and satisfied the relationship of (expression 1).

R[2/6]=0.4804

R[3/5]32 0.8993

R[3/5]−R[2/6]=0.4189 R[3/5]−R[2/6]≧0.15  (expression 1)

Gradient S[2/6] and S[3/5] gave the following values, and satisfied the relationships of (expression 2) and (expression 3).

S[2/6]=54.29

S[2/6]−70.32

S[3/5]−S[2/6]=−124.61

S[3/5]−S[2/6}≦−50  (expression 3)

The same calculation method was used and each parameter value was calculated from relationships between tensile elongation at break EB (%) and weight percentage (Pa) of olefin derived copolymers in resin composition (Table 6), in thermoplastic resin compositions of Comparative examples 3-8 and Comparative examples 9-14 in which olefin derived copolymers of Comparative example 1 and Comparative example 2 and polypropylene derived resins were blended, and polypropylene resin shown in Example 8.
