| 中文摘要 | we have synthesized macrocyclic polystyrene- (ps-) terminated ps star polymers via a core-cross-linking approach in this work. a tadpole-shaped macrocyclic ps-linear-ps copolymer was synthesized at first via click chemistry and atrp polymerization method. the "living" atrp initiating chain-ends of the tadpole-shaped copolymers were linked together via atrp polymerization with divinylbenzene to form a core-cross-linked macrocyclic star polymer. the number of arms attached to the macrocyclic star polymers was measured with nmr. and absolute molecular weights with gel permeation chromatography (gpc) with multiangle laser light scattering detector. these macrocyclic star polymers had a highly cross-linked core and many radiating arms. the shorter tadpole-shaped precursors caused core-cross-linked star polymers with higher molecular weights and more arm numbers. the macrocycle-terminated core-cross-linked star polymers showed two glass transition temperatures, one arising from the linear branches and another from the macrocycles. |
