The general treatment is proposed to investigate the explicit expressions of the average number of subchains with definite monomer sequences on the polymer skeleton, in which the AB + A(f) type polycondensation is chosen as the classical model of polymerization. The linear homo-polymers and star shape co-polymers are examined to derive the z-average mean-square radius of gyration, respectively, where the mass of monomers are taken into consideration. Furthermore, the z-average mean-square radius of gyration of mixture sample is calculated, in which the weight factors of the co-polymer and homo-polymer for the non-fractionated samples are examined analytically.
