PROCESS FOR POLYMERIZING CHLOROPRENE

摘要

1. A process for the continuous polymerisation of chloroprene and optionally up to 20% by weight, based on the monomer mixture, of one or more monomers capable of copolymerisation with chloroprene, in an aqueous alkaline emulsion in the presence of emulsifiers and initiators at 0 degree C to 60 degrees C, characterised in that the emulsifier used is a mixture of from 2.0 to 6.0% by weight of a salt of disproportionated abietic acid and from 0.1 to 1.0% by weight, based in each case on the total quantity of monomers, of a compound corresponding to the following formula see diagramm : EP0235636,P6,F1 wherein R1 and R2 denote, independently of one another, hydrogen or CH3 , m denotes a number from 0 to 14, n denotes a number from 0 to 13, p denotes a number from 0 to 2 and Y denotes hydrogen, Na or K and the total number of aliphatic carbon atoms is from 11 to 15.
