MASTER BLENDS INCLUDING AN ETHYLENE AND ALPHA-OLEFINE COPOLYMER AS A CARRIER AND CONTAINING VULCANISATION AGENTS

摘要

The invention relates to thermoplastic master blends including vulcanisation agents for rubbers selected from : so called sulphur-based vulcanisation systems; metal oxides-based vulcanisation systems; peroxides-based vulcanisation systems; resins- and/or soap-based vulcanisation systems; diamine-based vulcanisation systems, acceleration systems based on thio-urea derivatives, including as a carrier at least one ethylene and alpha-olefine copolymer (A) from the catalysis of a metallocene type, and a copolymer (B) of ethylene and unsaturated carboxylic acid ester. The invention also relates to a method for preparing said master blends containing vulcanisation agents that involves essentially using a multiple chamber blender.
