Abstract：The characteristic ratio of unperturbed mean-square radius of gyration 〈S2〉0/2xl2 of poly( methyl acrylate) chain, as a function of the molecule weight and the tactic, was investigated by the rotational isomeric state theory. The estimated results for poly( methyl acrylate) , polyst ryene and poly( methyl methacrylate)chains can describe the relation of the intrinsic viscosity with the tacticity.
