The polymerization of chloroprene leads to non-colored products when a mixture of 2.0 to 5.0% by weight of a salt of disproportionated abietic acid and 0.1 to 1.0% by weight, in each case relative to the total amount of monomer, of a compound of the formula ##STR1## in which R 1 and R 2 , independently of one another, denote hydrogen or CH 3 , n m denotes a number from 0 to 14, n n denotes a number from 0 to 13, n p denotes a number from 0 to 2, and n y denotes hydrogen, Na or K, and n the total number of aliphatic carbon atoms is 11 to 15, n is used as emulsifier, the emulsifiers having the advantage of being biologically degradable. |
