Temperature Effects on Grafting Reaction to Produce Methyl Methacrylate Grafted Polychloroprene Adhesive
AbstractPolychloroprene (PC) is a common contact adhesive which fails to provide adhesive properties at temperatures as higher as 700C. 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 700C. Â 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 700C. 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 800C was found to be with maximum adhesion properties.
