Novel Process for the Synthesis of Chlorinated Polyvinyl Chloride Using Unsaturated Polyvinyl Chloride ResinBy Saurabh K. Tiwari, Virendrakumar Gupta
Abstract: The present work is related to the process for the synthesis of a reactor made chlorinated polyvinyl chloride (CPVC) from commercially available thermally treated unsaturated PVC. The synthesis of CPVC is a two-step process. The first step is the controlled thermal treatment of the PVC to generate the unsaturation in the PVC chain. The second step is the chlorination of the thermally treated PVC in presence of an initiator and …

Synthesis of Brominated Poly (Isobutylene-co-Isoprene) Based Ionomers and Its ApplicationsBy Saurabh K. Tiwari, Virendra Kumar Gupta
Abstract: Reactive bromobutyl rubber and its modification have been studied in detail. These reactive bromobutyl rubber was converted to ammonium and phosphonium functionalized bromobutyl rubber using triphenyl phosphine (PPh3) and 4-Dimethylaminopyridine (4-DMAP). Mechanical properties of synthesized ionomers are found comparative with butyl rubber. Pharma stopper was made from synthesized phosphonium ionomer that may be useful for pharma industries due to its self-healing characteristics which can help to preserve the properties of …
