Mischpolymere aus AEthylen-Styrol sowie Verfahren zu ihrer Herstellung

摘要

A copolymer of ethylene and styrene containing 1-25% of styrene units is claimed and may be prepared by copolymerization of the monomers at 800-3000 atmospheres, and at 100-300 DEG C. in the presence of at least one catalyst of formulae (1) (2) (3) (4) where X is a phenyl or alkyl group and Y is H or an alkyl group. The catalyst may be (1) ditert.-butyl-or diethyl-peroxides or tert.-butyl hydroperoxide, (2) tert.-butyl-perbenzoate or peracetate or tert.-butyl per-2-ethylhexanoate, (3) octanoyl, acetyl or 2-ethylhexanoyl peroxides, or (4) isopropyl or isoamyl peroxydicarbonates. The copolymer may be formed into a film.
