In the polymerization of vinyl chloride, as in other radical polymeriza-tion processes, the chain transfer reaction plays a large part. The state of knowledge on the chain transfer of polyvinyl chloride (PVC) radicals to vinyl chloride and to PVC was

The ability of different organic additives to increase the bulk density (BD) and the free flow (FF) of PVC was investigated. PVC was treated by quarternary ammonium salts, low-molecular glycols, polyethylene glycols, polyethylene wax, stearic acid, b

Vinyl chloride (VC) as well as other vinyl monomers interact with oxygen of the air to give peroxide compounds. It is known that the course of this reaction has some influence on the production process of polyvinyl chloride (PVC) as well as on the pr

The cationic polymerization of vinyl chloride, vinylidene chloride, and cis- and trans- 1,2-dichloroethylenes with the use of Lewis acid-type catalysts has been studied. Vinylidene chloride is smoothly polymerized in the presence of ZnCl2 at 40°C to

Infrared spectroscopic and DTA measurements and chemical analysis have shown that during stabilization of PVC with organic and inorganic basic lead salts various reactions occur: (a) binding of the evolved HCl, by these salts with the formation of le
