Title: The heat treatment of shaped articles, particularly yarns, comprising an elastomeric polymer
Inventor: BOYER CLARENCE
IPC: D01F6/72
Filed: 1959-12-15
Abstract: The process of the parent Specification (wherein shaped structures of certain elastomeric linear polymers are subjected to heat treatment above 80 DEG C. but below their melting point and then cooled) is modified in that undrawn shaped articles comprising the same or another substantially linear segmented elastomeric polymer are heated, while substantially free of applied stretch, at 105 DEG  to 150 DEG C., preferably 110 DEG  to 130 DEG C., for at least 5 minutes and preferably not more than 10 hours. "Undrawn shaped articles" are defined as filaments and like products which have not been stretched beyond the elastic limit subsequent to their formation, although they may have been drawn to some extent during the actual spinning operation, before they are fully set.  "Segmented elastomers" are defined as elastomeric polymers comprising segments of a crystalline polymer having a melting point above 200 DEG C. alternating with segments of an amorphous polymer having a molecular weight above 600 and a melting point below 50 DEG C.  The crystalline polymer may be a polyurea, polyurethane, polyamide, polybisureylene or polyester. The amorphous polymer may be a polyester, a polyether or a polyhydrocarbon.  The crystalline segments generally make up about 10-40% by weight of the segmented elastomer, which generally has a molecular weight of at least 5,000.  The preferred elastomers contain bis-ureylene segments alternating with polyether or polyester segments.  In an example, samples of filaments formed by wet spinning a solution in dimethyl formamide of a diisocyanate-modified poly(tetramethylene oxide) glycol extended with hydrazine into water at 70 DEG C. are heated in an oven at 120 DEG C. without tension for periods ranging from 1/4 to 70 hours. The heat treatment improves the tenacity, stress decay and tensile recovery properties of the products.  Specification 849,154 and U.S.A. Specifications 2,813,775, 2,813,776 and 2,965,437 also are referred to.

Title: Method and apparatus for the production of foam plastic sheet
IPC: B29C48/10
Filed: 1965-10-12
Abstract: A tube 123 of foamed alkenyl aromatic resin, in particular foamed polystyrene, is extruded, and then biaxially stretched and cooled below its thermoplastic temperature by being drawn over a fluid-cooled mandrel 124 whose diameter may be 1.1 to 2 times, but is preferably greater than two times, the diameter of the extrusion orifice associated with nozzle 121.  The resin, preferably together with a nucleating agent, is fed via hopper 114 to barrel 115 and the blowing agent is fed by pump 118 from a reservoir 117.  The tube passes between fluid cooled rings 136, 1361 upstream of mandrel 124 and gas, e.g. air, is supplied by a central conduit 134 and is trapped between mandrel end 126 and the tube.  The gas acts as a lubricant between the mandrel and tube as well as providing a further cooling action.  The tube is subsequently cut by a knife 140 and is collected as a wound sheet to form a roll 143.  Draw-rolls 141, 142 may act to crush the surface cells of the sheet.  An alternative form of mandrel, Figs. 9-11 (not shown), comprises a chill ring (157) supplied with cooling fluid which enters port (168) and leaves port (167), and gaps (153), (158) which are supplied with gas to perform the function as mentioned above.  In a second embodiment, Figs. 1-6 (not shown), an auxiliary extruder (22), see Fig. 1 (not reproduced), <PICT:1102239/C3/1> is utilized, and guides (40-43) are provided to gradually flatten the tube after it is cut by a knife (39), see Figs. 3-6 (not reproduced). The mandrel (30), see Fig.2 (not reproduced), is internally cooled via conduits (55), (56) and gas is supplied through passageway (51) from a pump (35).  In a modification, Fig.7 (not shown), gas is supplied in a downstream direction to opening (74) via conduit (73). Among the alkenyl aromatic resins mentioned are the solid homopolymers of styrene or two or more of these homopolymers with minor amounts of polymerizable olefinic compositions such as divinylbenzene, methylmethacrylate or acrylonitrile.  Nucleating agents mentioned are finely divided silica, carbon black, calcium carbonate, indigo and unsaturated carboxylic acid-monovinyl aromatic copolymers used in amounts from 0.1 to 10, preferably 0.3 to 5% by weight of the polymeric ingredients.  In specific examples the resin is polystyrene, the nucleating agent is a styrene maleic anhydride copolymer containing copolymerized therein 70 parts by weight of styrene and 30 parts by weight of maleic anhydride and the blowing agent is n-Pentane.

Abstract: 988,743. Treating textiles. DOW CHEMICAL CO. Nov. 28, 1962, No. 45051/62 Heading D1L. A method of treating a tow bundle of acrylonitrile polymer aquagel fibres by countercurrently flowing water in at least two separate but intercommunicating water treating stages is characterized in that the tow is introduced into a first stage at one end of a bath; each stage sequentially intercommunicates through an opening at the point of physical separation between each stage which opening fits closely about and permits substantially squeezeless passage therethrough of the tow which permitting water communication between adjacent stages; the tow is passed in a sequential manner through each opening and through the water in each stage; the tow is withdrawn from the water in the last stage at the opposite end of the bath; at least a portion of fresh water is admitted at the last stage; a portion of used water is withdrawn from the first stage 7 and the water is passed from the last stage to the first stage such that at each point of separation between adjacent stages all of the water flows through and between the individual filaments in the tow bundle. As shown in Fig. 3 treating bath 7 is divided into four equal stages 8 that are separated by partitions 9. The bath may be a bath of aqueous wash liquid 15 for a multiple continuous filament tow bundle 11 of freshly wet spun polyacrylonitrile filaments. The tow 11 is introduced into the treating liquid 15 in the first stage of the bath by being passed under roller 12. The tow 11 is preferably in a relatively flat ribbon-like form and is sequentially passed through all the stages of the bath, traversing each of the stage-separating partitions 9 through the tow accommodating apertures 10 and is withdrawn from the bath around roller 13. The treating liquid is passed countercurrently through each of the stages of the bath against the tow. This is preferably done by gravity flow through stepped or inclined stages or it may be done by pump means. The liquid is admitted at the last stage through inlet 14 and is withdrawn in a spent condition through outlet 16. The treating liquid passes through the apertures 10 directly through and between the individual filaments in the tow 11. A preferred form of partition 9 is shown in Fig. 6 and comprises upper and lower sections 19, 20 the upper member 19 being capable of being spaced from the lower member 20 in either of slots 21, 22, 23 and resting on the tow under the action of gravity. The member 19 may be on either the upstream or downstream side of member 20. The tow 11 may be agitated in the bath by suitable reciprocating means or arrangements may be provided for internally circulating some of the treating liquid in each stage for transversely flushing the tow.
