| Abstract: | Living lincar polystyrene macromolecule anions which are sythesized by common anionic poly merization method are cross-linked and nucleated with divinylbenzene. Thus thirteen regular star-s haped branched polystyrene model compounds with four to eighty arms, which are of narrow molecular weight distribution and of constant sub-chain length, have been prepared by the present authors and characterized by GPC in conjunction with viscometer. |
