Synthesis and fractionation of copolymes of tri-n-butyltin methacrylate (TBTMA) with MMA have been investigated.The fractionated molecular weight and corresponding [Z] of copolymers and K and T values in Mark-Houwink equation of copolymers have been determined.In case of TBTMA:MMA=1:1(feed molar ratio),K=0.225,T=0.46,the distribution of molecular weight d is 2.32 and in case of TBTMA:MMA=1:2(feed molar ratio),K=1 69×10^-4,T=1.18,d=1.23.
