Grafting of methyl methacrylate (MMA) onto polychloroprene rubber latex (CRL) was carried out by emulsion polymerization using a redox initiator. The effects of the principal factors such as emulsifier, initiator and their concentrations and monomer/polymer ratio on monomer conversion, and grafting efficiency were studied. Infrared (FTIR) spectra, proton nuclear magnetic resonance (HNMR), and differential scanning calorimetry (DSC) analysis of the graft copolymer showed the occurrence of grafting. The surface-diffusion controlled process model was proposed to describe the grafting mechanism. The graft copolymer was blended with tackifier and filler for waterborne contact adhesive applications. The 180 degree peel strength of the above adhesive for canvas to other decoration materials was investigated.
