Abstract
Graft copolymerization of acrylic acid onto Poly vinyl chloride (PVC) was c arried out in nitrobenzene using di-(2-phenoxy ethyl) peroxy dicarbonate as an initiator. The effect of various parameters such as initiator, monomer concentrations, reaction temperature and time on percent grafting was exami ned. The graft copolymers were characterized by Viscosity, Infrared Spectro scopy (IR) and Thermogravimetry (TGA) and Differential Scanning Calorimetry (DSC). The thermal stability of graft copolymers increased whereas intrins ic viscosity decreased as percent grafting was increased. Maximum grafting of 3.0% was obtained. The activation energy and collision frequency factor for graft copolymerization was found to be 4.54 Kcal/mol and 0.8788 X 10(2) , respectively.
