An aqueous latex having good colloidal stability against coagulation upon the addition of ionic material is made by polymerizing (1) an aqueous suspension of chloroprene monomer containing about 0.5 to 5.0 parts of alpha, beta-unsaturated carboxylic acid monomer, based on total monomer, in the presence of 2-6 parts by weight of a protective colloid containing 0.1 to 6 parts by weight hydroxyethyl cellulose and from 0 to 2.9 parts by weight of polyvinyl alcohol.
