1. Vinyl chloride-acetate copolymer is produced by international advanced micro-suspension co-polymerization process. As putting vinyl acetate into rigid chain of PVC molecule to make the polarity of PVC molecule reduced and attraction force between molecules lowered, compared with PPVC of homogeneous polymerization, its gelating temperature and molten temperature have been reduced obviously (30-40°C).In addition, because of introducing ester base, it may increase solvent rate between resin and plasticizer, and improve adhesive force between resin and all kinds of adhesion basic material. 2. Uses: It is used widely as important material of reducing process temperature and increasing plasticization speed and improving product property in PVC automobile plastisol (including coating of preventing bottom disc from stone attacking, spot welding gel for body weld seal, filter core glue and buffered glue etc.), back-lined adhesive for PVC square blanket, printing ink
