Abstract

PVC is one of the world’s major polymers and a large amount of PVC is produced worldwide for its superior mechanical and physical properties. GRAFT COPOLYMERIZATION of PVC with monomers such as styrene has been examined to improve the thermal stability of PVC. This GRAFT COPOLYMERIZATION was carried out by ATOM TRANSFER RADICAL POLYMERIZATION (ATRP). In this method PVC was condensed with toluene in mild condition (toluene as arylating agent, AlCl3 complexed with nitrobenzene as catalyst and THF as diluent) and we used arylated PVC (PVC-ph) as a starting polymer and N-bromosuccinimide as a brominating agent to obtain polymers with bromine group. This brominated PVC was used as a macroinitiator. This macroinitiator can polymerize styrene in the presence of CuCl/bpy catalyst system in THF solvent at 90°C. The formation of the graft copolymer was confirmed with GPC, DSC, 1H NMR and FTIR spectroscopy. This approach using a macroinitiator is an effective method for the preparation of new materials.
