Graft copolymers mechanical forces, synthesis

The synthesis of block and graft copolymers by mechanical forces has bear earlier reviewed by many authors (4-10). This review is thus not intended to be exhaustive and a different approach has thus been takea The material is organized by state of matter rather than by the instruments used. Thus the authors hope to provide a descriptive mosaic for the parallel studies developing in different countries and in different facets of the field. Some of the original references may be difficult to procure so that more general secondary references are cited in some cases. 

Over last decades the synthesis of block and graft copolymers by mechanical forces has been studied by various researchers, and the recent development in this field has been reviewed by Casale and Porter (S). Pioneer works of ESR studies on low temperature reactions of the mechano-radicals were reported by Butyagin and his collaborators 34, 100). In this review presentation will be limited to ESR studies on polymerization initiated by the PTFE mechano-radical at low temperatures 101).
