Abstract: The bonding performance of adhesives in binary graft modification synthesized by neoprene(CR) and methyl methacrylate(MMA),and the effect on the properties of the graft neoprene adhesive about the copolymerization reaction temperature,the concentration of initiator and MMA,the influx mode of MMA and nitrogen and the concentration of the initial CR were studied.The optimum reaction condition and formulation were acquired.
