Gamma Radiation Induced Graft Copolymerization of Typical Monomers onto Poly (3-hydroxybutyrate)

The preparation of several graft copolymers obtained by radiation induced graft copolymerization of typical monomers onto poly (3hydroxybutyrate) is reviewed. The general mechanisms by which graft copolymerization reaction proceed under various irradiation conditions are described. Main attention is given to the structure, properties, synthesis and characterization of the graft product, as well as the comparison of methods, advantages, basic fundaments and the effect of reaction parameters on graft degree. Potential applications of the obtained products are also highlighted. Although the use of the graft copolymers is very promising, more efforts are needed to bring these copolymers to the pilot scale production and make them useful materials.
