SYNTHESIS AND STUDY OF COPOLYMERS OF METHYL METHACRYLATE WİTH OLIGOPROPYLENE MACROMONOMERS

The reaction of radical copolymerization oligopropylene macromonomer (M1) with methyl methacrylate (M2) has been carried out, the regularities and properties obtained products have studied. It found that values relative activity these monomers are r1=0.02 r2=12.2, respectively. fact value constant is close to zero indicates it not prone homopolymerization reactions only undergoes reactions. dependence some synthesized copolymer on their composition studied shown an increase in amount fragment formed from macromonomer, softening temperature intrinsic viscosity copolymers decrease, and, accordingly, a sharp decrease average molecular weight observed. This due passivity high probability chain transfer through macromonomer.
