Macromonomers of poly -1,3 (dioxolan) were synthesized, using the activated monomer method, which consists to polymerize 1,3-dioxolan in the presence of an unsaturated alcohol such as the 2 - hydroxypropylméthacrylate (2-hpma) (co- catalyst) and sulphuric acid (H2 SO4 ) as catalyst. The reaction was carried out under atmosphere , the macromonomer obtained was characterized by NMR 1 H, UV, GPC and FTIR. The product yielded is useful, thereafter, as precursor, to the preparation of grafted copolymers . In order to obtain grafted copolymers, we have prepared series of macromonomer samples having each one a different number.-average molecular weight.
