[0025] c is 0 to about 100, 1 to about 100, preferably O to about 40 and more preferably about 0 to about 15;
[0026] d is 0 to about 100, 1 to about 100, preferably O to about 40 and more preferably about 0 to about 15;
[0027] q is 0 to about 2;
[0028] r is 0 to about 2;
[0029] p is 1 to about 3 subject to the limitation that p+q+r=3; and

[0031] a' is 0 to about 100, 1 to about 100, preferably O to about 40 and more preferably about 0 to about 15;
[0032] b' is 0 to about 100, 1 to about 100, preferably O to about 40 and more preferably about 0 to about 15;
[0033] c' is 0 to about 100, 1 to about 100, preferably O to about 40 and more preferably about 0 to about 15;
[0034] d' is 0 to about 100, 1 to about 100, preferably O to about 40 and more preferably about 0 to about 15;
[0035] Y is H, or metal ion; and
[0036] One embodiment of the present invention includes up to about 0.5 to about 50 percent by weight of the total weight of monomers, of one or more additional monomer, preferable any acrylic acid/acrylate, methacrylic acid/methacrylate, or monomers such as acrylamides, vinyl acetate and styrene, which are copolymerizable with (i). Any organic acrylate or methacrylate can be employed as the comonomers in the composition. Examples of such monomers include, but are not limited to, acrylic acid and methacrylic acid or the derivatives such as methyl, ethyl, butyl, amyl, 2-ethylhexyl, cyclohexyl, vinyl, ally, hydroxyethyl, perfluoroethyl, isobornyl, phenoxyethyl, tetraethylene glycol, tripropylene glycol, trimethylolpropane, polyoxyalkylene.
[0037] According to still another aspect of the present invention further provides a network composition described above wherein the cross-linking agent is a polyfunctional vinlylidene monomer containing at least two unsaturated groups. Examples of polyfunctional vinlylidene monomers of the network composition is selected from the group consisting of butadiene, isoprene, divinyl benzene, allyl acrylates, polyalkylene glycol diacrylates and dimethacrylates. Other crosslinking agents include diallyl esters and dimethallyl esters and other crosslinking agents listed and described in U.S. Pat. No. 4,509,949 herein incorporated in its entirety by reference.
[0038] In still yet another aspect of the present invention, a network composition as described above is provided wherein the composition comprises about 40 to about 99, preferably 50 to about 85, more preferably about 60 to about 75 weight percent based on the total weight of the monomers of at least one anionic polymerizable ethylenically unsaturated monomer (I), about 0.5 to about 50, preferably about 5 to about 40, more preferably about 10 to about 30 weight percent based on the total weight of the monomers of the additional monomers and about 0.1 to about 10, preferably about 2 to about 8, more preferably about 3 to about 6 weight percent based on the total weight of the monomers of said cross-linking agent.
[0039] Both the acrylate cross-links and the polyether substituents are capable of hydrogen bonding with water and other hydroxylic solvents, increasing content of either, all other composition variables remaining constant, will tend to increase the water swellability of the resulting cross-linked network polymer. Because it is possible to vary the compositional parameters of the cross-linked network copolymers of the invention in an almost limitless fashion, some compositions are both water swellable and oil swellable while others are only water swellable or oil swellable, and some compositions will not be swellable with any of the solvents discussed herein. The amount of crosslinking present in the crosslinked network may be characterized with respect to the degree of swelling exhibited by the network in the fluid.
[0040] The cross-linked structure of the network of the present invention is effective to allow the network to be swollen from its original volume to a swollen volume that is a factor of from 1.01 to 5000, more preferably from 2 to 1000, and even more preferably from 5 to 500, times its original volume. The original volume of the network can be determined, for example, by extracting or evaporating all of the fluid component from the silicone composition of the present invention to leave the original volume, that is, the volume of the copolymer network in the absence of the fluid.
[0041] In one aspect of the present invention the network composition of the present invention can be swollen by a solvent such as water.
[0042] According to yet another aspect of the present invention a network composition comprising a reaction product of monomer (I) provided below and has a subscript p equal to 2 or 3, no additional cross linking agent is necessary. That is, a network composition comprising at least one anionic polymerizable ethylenically unsaturated monomer (I)
[0043] R3═H or alkyl of 1 to about 6 carbon atoms;
[0044] X=alkyl, aryl, or alkaryl diradical connecting group of 0 to about 9 carbon atoms; a is 0 to about 100;
[0045] b is 0 to about 100;
[0046] c is 0 to about 100;
[0047] d is 0 to about 100;
[0048] q is 0 to about 2;
[0049] r is 2 or 3;
[0050] p is 1 to about 3 subject to the limitation that p+q+r=3; and
[0051] Y and Z is H, or metal ion; and
[0052] In one embodiment of the present invention, the network composition is a solid or solid gel material, typically having a creamy consistency, wherein the copolymer network acts as a means for gelling the fluid to reversibly impart characteristics of a solid to the fluid. At rest, the network polymer composition exhibits the properties of a solid gel material. The network polymer composition of the present invention exhibits high stability and resistance to syneresis, that is, the composition exhibits little or no tendency for fluid to flow from the composition and imparts high stability and syneresis resistance to personal care compositions, which include the silicone composition as a component. The high stability and syneresis resistance persists with prolonged aging of such silicone compositions and personal care compositions. However, fluid may be released from the network by subjecting the network polymer composition to a shearing force, such as, for example, by rubbing the composition between one's fingers, to provide improved sensory feel characteristic of the fluid component of the silicone material.
[0053] Water (or a water equivalent such as a non-aqueous hydroxylic solvent), siloxane, linear or cyclic, or lipophillic fluid (oil swelling agent, oil swellable) may be used as the swelling agent. Lipophilic fluids suitable for use as the fluid component of the composition of the present invention are those compounds or mixtures of two or more compounds that are in the liquid state at or near room temperature, for example, from about 20° C. about 50° C., and about one atmosphere pressure, and include, for example, silicone fluids, hydrocarbon fluids, esters, alcohols, fatty alcohols, glycols and organic oils. In a preferred embodiment, the fluid component of the composition of the present invention exhibits a viscosity of below about 1,000 cSt, preferably below about 500 cSt, more preferably below about 250 cSt, and most preferably below 100 cSt, at 25° C.
[0054] In another embodiment of the invention, the copolymer network is a crosslinked network that is insoluble in various fluid components, but that is capable of being swollen by the fluid. The amount of crosslinking present in the crosslinked network may be characterized with respect to the degree of swelling exhibited by the network in the fluid. In another preferred embodiment, the crosslinked structure of the network is effective to allow the network to be swollen by water, from its original volume to a swollen volume that is a factor of from 1.01 to 5000, more preferably from 2 to 1000, and even more preferably from 5 to 500, times its original volume. The original volume of the network can be determined, for example, by extracting or evaporating all of the fluid components from the network polymer composition of the present invention to leave the original volume, that is, the volume of the copolymer network in the absence of the fluid. In another preferred embodiment, the crosslinked structure of the network is effective to allow the network to be swollen by a lipophilic fluid, from its original volume to a swollen volume that is a factor of from 1.01 to 5000, more preferably from 2 to 1000, and even more preferably from 5 to 500, times its original volume. The original volume of the network can be determined, for example, by extracting or evaporating all of the fluid components from the network polymer composition of the present invention to leave the original volume, that is, the volume of the polyacrylate siloxane copolymer network in the absence of the fluid.
[0055] In another preferred embodiment, the crosslinked structure of the network is effective to allow the network to be swollen by a low molecular weight silicone fluid, such as, for example, decamethylcyclopentasiloxane, from its original volume to a swollen volume that is a factor of from 1.01 to 5000, more preferably from 2 to 1000, and even more preferably from 5 to 500, times its original volume. The original volume of the network can be determined, for example, by extracting or evaporating all of the fluid component from the network composition of the present invention to leave the original volume, that is, the volume of the copolymer network in the absence of the fluid.
[0056] In yet another embodiment of the present invention, the fluid component of the present invention comprises an emollient compound. Suitable emollient compound include any fluid that provides emollient properties, that is, that when applied to skin, tend to remain on the surface of the skin or in the stratum corneum layer of the skin to act as lubricants, reduce flaking and to improve the appearance of the skin.

[0058] Another aspect of the present invention is directed to a method for producing network polymer compositions of the present invention. Using the monomers described above, the monomers are polymerized under free radical polymerization conditions. The polymerizations are conducted in various solvents using catalysts and temperatures known in the art for polymerizing acrylates.

Examples of aryls include phenyl and naphthalenyl. Examples of aralkyls include benzyl and phenethyl. Examples of arenyls include tolyl and xylyl.
[0066] Other than in the working examples or where otherwise indicated, all numbers expressing amounts of materials, reaction conditions, time durations, quantified properties of materials, and so forth, stated in the specification and claims are to be understood as being modified in all instances by the term "about" whether or not the term "about" is used in the expression.
[0067] It will be understood that any numerical range recited herein includes all sub-ranges within that range and any combination of the various endpoints of such ranges or sub-ranges. As used herein, integer values of stoichiometric subscripts refer to molecular species and non-integer values of stoichiometric subscripts refer to a mixture of molecular species on a molecular weight average basis, a number average basis or a mole fraction basis. In the case of mixtures of the compounds of the present invention, it should be readily apparent that the stoichiometric subscripts of mixtures would have average values for the subscripts that may be either integral or non-integral in contrast to those of pure compounds.
[0068] It will be further understood that any compound, material or substance which is expressly or implicitly disclosed in the specification and/or recited in a claim as belonging to a group of structurally, compositionally and/or functionally related compounds, materials or substances includes individual representatives of the group and all combinations thereof.
[0069] The term "cross-linked polymers" means polymer molecules which are built from monomers which are linked together at many points other than their ends and as a result molecules with large size form and the material is non-pourable solid or gel-like which cannot be dissolved in any solvent. Cross-links are bonds that link one polymer chain to another. They can be covalent bonds or ionic bonds. "Polymer chains" can refer to synthetic polymers or natural polymers. In synthetic polymers, crosslinking refers to the use of cross-links to promote a difference in the polymers' physical properties.
[0070] The copolymers in our invention are "non-crosslinked", which means that their monomers are either not linked together at points other than their ends or the linkages between the polymers are so few that the copolymer is either liquid or can be dissolved in at least one solvent.
[0071] Reference is made to substances, components, or ingredients in existence at the time just before first contacted, formed in situ, blended, or mixed with one or more other substances, components, or ingredients in accordance with the present disclosure. A substance, component or ingredient identified as a reaction product, resulting mixture, or the like may gain an identity, property, or character through a chemical reaction or transformation during the course of contacting, in situ formation, blending, or mixing operation if conducted in accordance with this disclosure with the application of common sense and the ordinary skill of one in the relevant art (e.g., chemist). The transformation of chemical reactants or starting materials to chemical products or final materials is a continually evolving process, independent of the speed at which it occurs. Accordingly, as such a transformative process is in progress there may be a mix of starting and final materials, as well as intermediate species that may be, depending on their kinetic lifetime, easy or difficult to detect with current analytical techniques known to those of ordinary skill in the art.
[0072] Reactants and components referred to by chemical name or formula in the specification or claims hereof, whether referred to in the singular or plural, may be identified as they exist prior to coming into contact with another substance referred to by chemical name or chemical type (e.g., another reactant or a solvent). Preliminary and/or transitional chemical changes, transformations, or reactions, if any, that take place in the resulting mixture, solution, or reaction medium may be identified as intermediate species, master batches, and the like, and may have utility distinct from the utility of the reaction product or final material. Other subsequent changes, transformations, or reactions may result from bringing the specified reactants and/or components together under the conditions called for pursuant to this disclosure. In these other subsequent changes, transformations, or reactions the reactants, ingredients, or the components to be brought together may identify or indicate the reaction product or final material.
[0073] In describing the products of the present invention as a reaction product of initial materials reference is made to the initial species recited and it is to be noted that additional materials may be added to the initial mixture of synthetic precursors. These additional materials may be reactive or non-reactive. The defining characteristic of the instant invention is that the reaction product is obtained from the reaction of at least the components listed as disclosed. Non-reactive components may be added to the reaction mixture as diluents or to impart additional properties unrelated to the properties of the composition prepared as a reaction product. Thus for example finely divided solids such as pigments may be dispersed into the reaction mixture, before during or after reaction to produce a reaction product composition that additionally comprises the non-reactive component, e.g. a pigment. Additional reactive components may also be added; such components may react with the initial reactants or they may react with the reaction product; the phrase "reaction product" is intended to include those possibilities as well as including the addition of non-reactive components.
[0074] Other optional ingredients may be added in the compositions of the present invention including coupling agents, e.g., silane coupling agents, curing aids, e.g., including activators, retarders and accelerators, processing additives such as oils, plasticizers, tackifying resins, silicas, other fillers, pigments, fatty acids, zinc oxide, waxes, antioxidants and anti-ozonants, peptizing agents, reinforcing materials such as, for example, carbon black, and so forth. Such additives are selected based upon the intended use and such selection is within the knowledge of one of skill in the art, as are the required amounts of such additives known to one of skill in the art.
[0075] Other embodiments of the invention will be apparent to those skilled in the art from a consideration of this specification or practice of the invention disclosed herein. It is intended that the specification and examples be considered as exemplary only, with the true scope and spirit of the invention being defined by the following claims.
[0076] The compositions of the present invention can be used commercially as a demulsifying agents, in agricultural compositions including fertilizers, in cosmetics and personal care products, in household cleaners, in coating compositions such as waxes and the like, in water processing apparatuses as well as other products.
