The non-rubber substances present in natural rubber (NR) latex seem to have an influence on the rate of polymerization reaction, degree of grafting
grafting efficiency of the graft copolymerization reaction of Methyl Methacrylate on to natural rubber.The released amino acids on enzymatic destruction of phospholipid/protein barrier in natural rubber latex may probably by the cause for the improvement of the reaction kinetics; such that reaction under redox conditions could be conducted without purification of the monomer with inhibitors. Presence of emulsifier, type of enzyme, monomer diffusion time in rubber particle, size of the particle are shown to have an influence on the physical properties of the final product.H NMR has been used to study the composition of the final product.
