Abstract:

Polychloroprene (PC) is a common contact adhesive which fails to provide adhesive properties at temperatures as higher as 70°C. Graft copolymerization of Methyl Methacrylate (MMA) to PC is investigated in the present studies to enhance adhesive properties of PC for its use at elevated temperatures e.g., above 70°C. MMA is commonly used as a grafted monomer in many grafting reactions to incorporate and/or enhance properties of polymers. The graft reactions were carried out in a batch copolymerization reactor at various grafting temperatures. Viscosity of the final reaction mixture was determined using a Brookfield Rheometer to check whether the reaction has taken place or not. The grafting reaction was observed to be not initiated below 70°C. Adhesive strength of the virgin and grafted polymers was analyzed by using standard peel resistance tests on leather samples by Universal Testing Machine. The grafted polymer adhesive produced at 80°C was found to be with maximum adhesion properties.
