The use of the poly(3-hydroxyalkanoates) in copolymer synthesis has received much interest, as the microbial polyester segments can bring interesting properties, such as biodegradability and biocompatibility. The synthesis, properties, and applications of graft copolymers containing poly(3-hydroxyalkanoates) as main chain or branches are reviewed here, with emphasis on the different preparation methods, which fit into the three main synthesis strategies of graft copolymers: “grafting onto”, “grafting from”, and “grafting through” or macromonomer methods.Key words: poly(3-hydroxyalkanoates), graft copolymer, synthesis, properties, applications.

Polysaccharides are bio-degradable, inexpensive and easily available from consistent agricultural resources. Polysaccharides and their derivatives represent a group of polymer widely used in pharmaceutical and biomedical fields. The biodegradability of natural polymers reduces their shelf life. Grafting copolymerization technique is a most effective fascinating way for chemical modification of native characteristics of polysaccharides with maximum possibilities for improving the properties of polysaccharides and enhanced the range of exploitation.While the major difficulty facing us during synthesizing a graft copolymers reaction, is the lack of commercial methods of synthesis and lower percent graft yield. It is well known that the most important methods of synthesis engage the employ of chemical free radical initiator i.e. conventional based methods. Graft copolymerization through γ-radiation method is a better method of grafting in comparison to a chemical method and exhibits a great potential to synthesize the graft copolymers by virtue of its higher efficiency, low cost, higher thermal stability as well as enhanced the yield of the graft copolymer. Future prospective of irradiation technique would be significant impacts to develop of polymerization.

Molecular Weights

An attempt was made to prepare well-defined graft copolymers by the coupling reaction between acyl chloride groups located along the backbone chain and monohydroxy-terminated grafts prepared separately. The molecular weights and the parameters of heterogeneity in chemical composition of the products were determined by light scattering and osmometry. The determination of molecular characteristics revealed that the degree of grafting was low. The results therefore could not be confronted with a statistical model at this stage. The problems encountered in the synthesis, e.g., gel formation, and the data relating to the soluble products are discussed.
