Abstract
An uncured chlorinated polyethylene elastomer having a molecular weight distribution of about 6-13, as determined by the ratio of Mw/Mn where Mw represents the weight average molecular weight and Mn represents the number average molecular weight, a chlorine content of about 20-28% by weight, a Mooney viscosity value, determined according to ASTM D 1646-81, ML.sub.(1+4) at 100.degree. C., of about 15-36; and, optionally, a sulfur content of about 0.2-2% by weight and a process for their preparation.
