Thermoplastic elastomeric carbon monoxide/olefin copolymers
摘要:
Linear, thermoplastic, elastomneric copolymers of carbon monoxide and olefinically unsaturated compounds have an alternating sequence of repeating units and an average molecular weight Mw of the copolymers of from 80,000 to 1,200,000, binary, linear, alternating carbon monoxide/ethylene copolymers being excluded.
