Abstract

The chlorines in chlorosulfonated polyethylene have been characterized by kinetic analysis according to the method of Salomon. It is found that 2.7% of the total chlorine is primary, 89.8% secondary, 3.5% tertiary, and 4% is sulfonyl chloride. These results are in accord with statistical calculations based on a polyethylene model containing the same methylene‐to‐methyl group ratio as the polyethylene precursor. The types and approximate quantities of dichlorides in the chlorosulfonated polyethylene have been determined by reactions with potassium iodide and zinc dust

## Abstract Chlorosulfonated polyethylene (CSM) has been prepared by the gas‐solid method in a tank reactor using chlorinated polyethylene (CPE) and a gaseous mixture of chlorine and dioxide sulfur. Sulfur content of CSM determined by element analysis is used as a reference for the quantitative det
