The solution, thermal, and UV absorbance properties were investigated as a function of number of branched polystyrene chains on the [60]fullerene core. The solution viscosity (intrinsic viscosity) of the [60]fullerene-modified polystyrene decreased with the number of branching due to molecular entanglement. The better coating property of the [60]fullerene-modified polystyrene compared with those of the polystyrene/[60]fullerene mixtures seems to arise from a lower aggregation state of the [60]fullerene core induced by the branched polystyrene chain. An increase in the glass transition temperature of the modified polystyrene with the number of branched chains was observed as well. 한국섬유공학회 플러렌 변성 폴리스티렌의 물성에 관한 연구 Studies on the Physical Properties of Fullerene-Modified Polystyrenes Article 2 한국섬유공학회지, v.41, no.5, pp.358 - 364 한국섬유공학회지 41 5 358 364 kci ART001086830 fullerene polystyrene anionic polymerization branching fullerene polystyrene anionic polymerization branching
