Polyvinyl kolorayidi (PVC) ndi polima polima ndi vinyl kolorayidi monoma (VCM) mu peroxide, azo pawiri ndi oyambitsa ena kapena molingana ndi ufulu kwakukulu ma polymerization limagwirira pansi pa kuwala ndi kutentha.Vinyl chloride homopolymer ndi vinyl chloride copolymer onse pamodzi amatchedwa vinyl chloride resin.
PVC inali pulasitiki yayikulu kwambiri padziko lonse lapansi, yomwe imagwiritsidwa ntchito kwambiri.Amagwiritsidwa ntchito kwambiri muzomangira, zinthu zamafakitale, zofunikira zatsiku ndi tsiku, zikopa zapansi, matailosi apansi, zikopa zopanga, mapaipi, mawaya ndi zingwe, filimu yonyamula, mabotolo, zinthu zotulutsa thovu, zida zosindikizira, ulusi ndi zina zotero.
Malinga ndi kukula kwa ntchito zosiyanasiyana, PVC ikhoza kugawidwa mu: general-purpose PVC resin, high degree of polymerization PVC resin ndi cross-linked PVC resin.General cholinga PVC utomoni aumbike ndi polymerization wa vinilu kolorayidi monoma pansi zochita za initiator;Mkulu polymerization digiri PVC utomoni amatanthauza utomoni polymerized powonjezera unyolo kukula wothandizira mu vinilu kolorayidi monoma polymerization dongosolo;Crosslinked PVC resin ndi utomoni wopangidwa ndi polymerized powonjezera cholumikizira chokhala ndi diene ndi polyene mu vinyl chloride monomer polymerization system.
Malinga ndi njira yopezera vinyl kolorayidi monoma, akhoza kugawidwa mu njira kashiamu carbide, njira ethylene ndi kunja (EDC, VCM) monomer njira (mwachikhalidwe, ethylene njira ndi kunja monoma njira ndi pamodzi amatchedwa ethylene njira).
