Abstract
1517099 Elastic polymer compositions ABBOTT LABORATORIES 25 Aug 1976 [26 Aug 1975] 35418/76 Headings C3B C3M and C3R Copolymer mixtures having elastic properties comprise (1) 10-90% radial block copolymer of 60-85% butadiene and 40-15% styrene having an average molecular weight of at least 150,000 and (2) 90-10% of a polymeric material selected from elastomeric polyolefins, olefin copolymers and terpolymers, vinyl acetate copolymers, polyether and polyester elastomers, acrylics, thermoplastic epoxies, styrene polymers, polycarbonates, acetal resins, polyamides, vinyl chloride polymers, chlorinated polyethylene and mixtures thereof. Exemplified polymeric materials are chlorinated polyethylene and mixtures thereof with polyether and polyester urethane elastomers. The compositions may be moulded into pharmaceutical sealing components, container closures, syringe plunger sealing rings and syringe bulbs.
