摘要
首次探索了二价 (t-C4H9C5 H4) 2 Sm对 4 -乙烯基吡啶的催化聚合性能 ,发现二价 (t-C4H9C5 H4) 2 Sm可以单组分高效催化 4 -乙烯基吡啶的聚合 ,而且聚合物分子量一般在 1 0× 1 0 5 以上。在 2 0℃至 70℃温度范围内 ,催化聚合活性随单体浓度和聚合温度的提高而提高。
Polymerization of 4-vinylpyridine (4VP) catalyzed by divalent (t-C_4H_9C_5H_ 4)_2Sm has been studied. It is found that the divalent (t-C_4H_9C_5H_4)_2S m is an effective catalyst for 4VP polymerization and the polymer's molecular we ight may exceed 10×10~5. The catalytic activity increases as the monomer conce ntration and polymerization temperature are raised.
