Abstract: An oriented elastomeric filament spun from a thermoplastic elastomeric material selected from the group consisting of a block copolymer of polybutylene terephthalate and polytetramethylene glycol, a block copolymer of polybutylene terephthalate/polybutylene isophthalate and polyethylene glycol/polypropylene glycol, a block copolymer of polybutylene terphthalate/polyhexene terephthalate and polytetramethylene glycol, and a block copolymer of polyurethane ad polytetramethylene glycol, the mole fraction of the polybutylene terephthalate, polybutlene terephthalate/polybutylene isophthalate and polybutylene terephthalate/polyhexene terphthalate in the block copolymers is less than 0.5, the elastomeric filament is further oriented after the spinning by stretching at temperatures between 20.degree. C. to 120.degree. C.

Abstract: A vehicle seat suspension has a thin high strength elastomeric membrane. The membrane is formed from block copolymer material by a process in which a sheet is extruded and tensioned to orient molecules in a select direction with respect to the membrane; the oriented membrane is annealed to retain the orientation during cyclical deformation of the membrane. The sheet form membrane is adapted to be connected with respect to a vehicle seat assembly frame and to serve as a backing for foam seating material and wherein the oriented structure of the membrane provides a two stage modulus in the direction of the orientation for providing static and dynamic load support characteristics which impart passenger comfort without increasing the weight of a seat assembly.

Abstract: A thin vehicle seat assembly having a tubular seat and back rest frame, seat and back rest cushion in the form of woven mats and means for attaching the mats to the seat and back rest frames. The woven mats comprise Hytrel elastomeric filaments extending perpendicular to each other and with the mats being prestretched in both directions to at least a 5-10% elongation prior to attachment to their respective frames.

Abstract: A thermoplastic blend of polyethylene terephthalate, a polyester elastomer, and an aromatic phosphite. The polyblend has greatly improved impact strength.

Abstract: An evaporative fuel control canister device containing a quantity of fuel-absorbing material which includes EPDM elastomeric foam for improved absorption of both fuel vapor and liquid fuel.

Abstract: A high impact thermoplastic polyblend of a polyethylene terephthalate, a polyester elastomer, and an aromatic phosphite. The aromatic phosphite when added in amounts up to as much as about 5 percent by weight of the total polyblend composition causing grafting of the polyester elastomer onto the polyethylene terephthalate chains producing a thermoplastic polyblend composition having superior impact strength.

Abstract: Dicumyl peroxide-dimaleimide cured EPDM elastomers can be molded to molded nylon articles so that the EPDM strongly adheres to the nylon. This practice is particularly useful in molding EPDM gaskets to nylon heat exchanger tanks.

Abstract: The disclosure relates to a vehicle seat assembly comprising a tubular frame means for a seat and backrest, a seat and backrest comprised of side by side elastomeric filaments prestretched across the seat frame and backrest frame and secured to the frame portions and a cover means to cover the seat and backrest whereby a thin seat is provided.

Abstract: A thermal sensing element containing a heat responsive material having a very high negative coefficient of thermal expansion. The heat responsive material contained therein is a methanol saturated copolymer of hexafluoropropylene and vinylidene fluoride. This thermal sensing element can detect minute temperature changes and can be packaged in a compact container for use in applications where space is limited.

Abstract: In a preferred embodiment, polyvinyl chloride resin plasticized with aliphatic carboxylic acid esters is imparted with superior flame and fire retardancy by a synergistic fire retarding additive. The additives of the invention comprise boric acid in combination with zinc oxide and/or zinc phosphate. These constituents together provide greater fire retardancy to the plasticized PVC than the sum of the effects of each constituent employed alone.

Abstract: In an exemplary embodiment a high temperature and oil resistant elastomer composition includes the peroxide-induced reaction product of, by weight, 100 parts ethylene-propylene-diene rubber, about 20 parts of a suitable crosslinking monomer, about 8 parts of a chlorinated organic material such as Chlorowax LV, about 10 parts of a suitable hindered phenolic antioxidant 10 to 15 parts zinc oxide and 5 to 8 parts magnesium oxide. The elastomer formulation may optionally contain suitable reinforcing and/or semireinforcing fillers and processing oils. A similar ethylene-propylene rubber formulation may be prepared. The resulting elastomer formulations have remarkable oil resistance and retain a significant elongation even after aging at 177.degree. C. (350.degree. F.) for 168 hours.
