Abstract
The rate of dehydrochlorination at 190°C of vinyl chloride/allyl chloride copolymers decreases with increasing content of allyl chloride. In agreement with the hypothesis that this is due to the blocking action of the CH2CI side groups, copolymer samples degraded at 170°C give a UV spectrum showing a greater preponderance of short polyene sequences than is found for the vinyl chloride homopolymer.
