Polyvinyl chloride (PVC) ipolymer yakashongedzwa nevinyl chloride monomer (VCM) mu peroxide, azo compound uye mamwe ekutanga kana zvinoenderana nemahara radical polymerization maitiro pasi pekuita kwechiedza nekupisa.Vinyl chloride homopolymer uye vinyl chloride copolymer dzinonzi pamwe chete sevinyl chloride resin.
PVC yaimbova yakakura pasi rose-chinangwa chepurasitiki, iyo yaishandiswa zvakanyanya.Inoshandiswa zvakanyanya mukuvaka, zvigadzirwa zvemaindasitiri, zvinodiwa zvezuva nezuva, dehwe repasi, mataira epasi, dehwe rekugadzira, pombi, waya netambo, firimu rekurongedza, mabhodhoro, zvinhu zvinopupuma, zvekuisa chisimbiso, fiber uye zvichingodaro.
Zvinoenderana neyakasiyana chiyero chekushandisa, PVC inogona kukamurwa kuita: general-chinangwa PVC resin, yakakwirira dhigirii yepolymerization PVC resin uye muchinjiko-yakabatana PVC resin.General chinangwa PVC resin inoumbwa ne polymerization yevinyl chloride monomer pasi pechiito cheinitiator;Yakakwira polymerization degree PVC resin inoreva resin polymerized nekuwedzera cheni yekukura mumiriri muvinyl chloride monomer polymerization system;Crosslinked PVC resin is resin polymerized nekuwedzera crosslinking agent ine diene uye polyene muvinyl chloride monomer polymerization system.
Zvinoenderana nenzira yekuwana vinyl chloride monomer, inogona kukamurwa kuita calcium carbide nzira, ethylene nzira uye kunze kwenyika (EDC, VCM) monomer nzira (yakajairika, ethylene nzira uye kunze kwenyika monomer nzira dzinonzi pamwe chete se ethylene nzira).
