PROCESS FOR THE PREPARATION OF LOW MOLECULAR WEIGHT ETHYLENE/VINYL ACETATE COPOLYMERS

摘要

A process for the production of an ethylene/vinylester copolymer having a molecular weight of from 500 to 10,000, and intrinsic viscosity numbers of 0.1 to 0.5 dl/g, determined in p-xylene at 25.degree.C, wherein ethylene and vinyl ester are polymerised radically at a temperature of from 10 to 200.degree.C and a pressure of from 10-700 bars in the presence of from 0.2 to 5 % by weight of acetaldehyde, based on the quantity of the initial monomers.
