Gamma-Ray Induced Polymerization of Vinyl Monomers in Bagasse

Vinyl monomers such as vinyl acetate, vinyl chloride, methyl methacrylate and styrene etc., can be polymerized without catalyst into the composites of bagasse material by gamma-radiation induced in situ liquid polymerization process. The fundamental factors, such as polymerization-rate, effect of swelling agent, molecular weight of vinyl polymers and graft reaction between bagasse cellulose and vinyl polymers, have been investigated and discussed. The use of suitable low G-value polar swelling agents and the application of suitable gamma dose-rate are two key factors found to control the smooth in situ liquid polymerization system of vinyl monomers in bagasse.
