O le Polyvinyl chloride (PVC) o se polymer ua polymerized e le vinyl chloride monomer (VCM) i le peroxide, azo compound ma isi initiators poʻo le tusa ai ma le free radical polymerization mechanism i lalo o le gaioiga a le malamalama ma le vevela. O le vinyl chloride homopolymer ma le vinyl chloride copolymer e taʻua faʻatasi o le vinyl chloride resin.
Sa avea muamua le PVC ma palasitika lautele aupito tele i le lalolagi, lea sa lautele lona faʻaaogaina. E lautele lona faʻaaogaina i mea faufale, oloa gaosi, mea e manaʻomia i aso uma, paʻu fola, taila fola, paʻu faʻapitoa, paipa, uaea ma uaea, ata afifi, fagu, mea faʻapupula, mea faʻamaufaʻailoga, alava ma isi mea faʻapena.
E tusa ai ma le lautele o le faʻaoga, e mafai ona vaevaeina le PVC i ni vaega se lua: resin PVC faʻamoemoega lautele, resin PVC maualuga le polymerization ma le resin PVC faʻafesoʻotaʻi. O le resin PVC faʻamoemoega lautele e fausia e ala i le polymerization o le vinyl chloride monomer i lalo o le gaioiga a le initiator; O le resin PVC maualuga le polymerization e faʻatatau i le resin polymerized e ala i le faʻaopoopoina o le chain growth agent i totonu o le vinyl chloride monomer polymerization system; O le resin PVC faʻafesoʻotaʻi o se resin polymerized e ala i le faʻaopoopoina o le crosslinking agent o loʻo i ai le diene ma le polyene i totonu o le vinyl chloride monomer polymerization system.
E tusa ai ma le auala e maua ai le vinyl chloride monomer, e mafai ona vaevaeina i le auala o le calcium carbide, auala o le ethylene ma le auala o le monomer mai fafo (EDC, VCM) (e masani ona taʻua le auala o le ethylene ma le auala o le monomer mai fafo o le auala o le ethylene).
