The molecular weight measurement has shown that the weight average molecular weight, MBAR(w) of the copolymers are all above 10(6) and their molecular weight distributions are monomodal and narrow (MBAR(w)/MBAR(n)<4). Thermal properties of these copolymers measured by DSC and TGA exhibited to be intermediate between those of the two corresponding homopolymers.
