GRAFTED AND CROSSLINKABLE PULVERULENT THERMOPLASTIC POLYOLEFIN COMPOSITION WHICH HAS ELASTICITY AND FLEXIBILITY PROPERTIES

摘要

A bulk polymerized grafted and crosslinkable thermoplastic polyolefin powder composition having elasticity and flexibility properties, which is in the form of a powder intended for the production of flexible coatings by free flow over a hot mold, characterized in that it contains: a) from 100 to 5 % by weight and preferably from 80 to 20 % by weight of at least one homopolymer of ethylene and/or at least one copolymer containing at least 50 molar % of ethylene; b) from 0 to 95 % by weight and preferably from 20 to 80 % by weight of at least one thermoplastic elastomer; c) from 0.1 to 15 parts by weight and preferably from 0.5 to 10 parts by weight of a grafting agent, per 100 parts by weight of the accumulated components "a" and "b". This powder composition is suitable for the production of flexible coatings by its free flow over a hot mold.
