Chlorinated polyvinyl chloride (CPVC) bụ ihe polymer enwetara ka emechara chlorination nke PVC ọzọ.Njirimara anụ ahụ na nke kemịkal na-agbanwe nke ukwuu: na mmụba nke ọdịnaya chlorine, mmebi nke yinye molekụla na-abawanye na kristal na-ebelata;polarity nke molekụla yinye na-abawanye, intermolecular ike na-abawanye, thermal deformation okpomọkụ na-abawanye nke ukwuu, na n'ibu Njirimara na-enwekwukwa.
