I-Polyvinyl chloride (PVC), evame ukwaziwa nge-PVC, iyi-polymer eguquguqukayo esetshenziswa ezimbonini ezahlukahlukene. Ikhiqizwa nge-polymerizing vinyl chloride monomer (VCM) ngokusebenzisa indlela ye-polymerization yamahhala ngosizo lwama-peroxides, ama-azo compounds noma ezinye iziqalisi, kanye nokukhanya nokushisa. I-PVC ihlanganisa ama-homopolymers e-vinyl chloride kanye nama-copolymers e-vinyl chloride, eqoqwe abizwa ngokuthi ama-vinyl chloride resins. Ngezakhiwo zayo ezivelele nokuvumelana nezimo, i-PVC isiphenduke into ekhethwayo ezinhlelweni eziningi.
