VERFAHREN ZUR VISKOSITÄTSÄNDERUNG VON COPOLYMEREN AUS ETHYLEN UND UNGESÄTTIGTEN CARBONSÄUREN

摘要

The viscosity of copolymers of a) ethylene, b) C1-C8 acrylates, C1-C8 methacrylates, or vinyl esters of C1-C8 carboxylic acids, and c) at least one alpha, beta-unsaturated carboxylic acid of 3-12 carbon atoms selected from the group consisting of monocarboxylic acids, dicarboxylic acids, and monoesters of dicarboxylic acids is increased, while maintaining gel content at a level of less than 3%, by treatment with a mixture of an organic peroxide and a chromium (III) salt.
