【摘要】 应用稀土配位催化剂Ｎｄ（ｎａｐｈ）３－Ａｌ（ｉ－Ｂｕ）３，在不同的条件下，可以制得白色和黄色的聚苯乙烯粉末，作者对两种聚苯乙烯的结构进行了ＩＲ、１３Ｃ－ＮＭＲ、１Ｈ－ＮＭＲ分析。证明了白色和黄色聚苯乙烯是无规聚合物，黄色聚苯乙烯存在－Ｃ（ＣＨ３Ｃ６Ｈ５）－Ｃ（ＣＨ３Ｃ６Ｈ５）－的结构。更多还原

【Abstract】 Polystyrene extracted from rare-earth coordination catalyst yields a white or yellow powder with the variation of polymerization conditions. The author studied the structure of polystyrene by IR、13C-NMR、1H-NMR. The white or yellow powder showed irregular structrue.-C-C(CH3C6H5)-C(CH3CH5)-was found in the macromolecule chain of the yellow polystyrene.更多还原
