摘要
本文以(Ph_3P)_2PdCl_2作催化剂,合成出聚二苯丁二炔和二苯丁二炔与苯乙炔共聚物。均聚物及共聚物产率都在90%以上,均聚物分子量为900,二苯丁二炔与苯乙炔最佳摩尔比为1/2(数均分子量为1205)。结构分析表明,均聚物及共聚物均具有反—反式结构。
In this paper,polydiphenylbutadiyne(1)and phenylacetylene-(?)iphenyl-butadiyne copolymer(2)are synthesised using(Ph_3P)_2PdCl_2 as catalyst.In the copolymerization,the best mole ratio of two monomers diphe-nylbutadiyne and phenylacetylene is 1/2.The catalytic homopolymerizationof diphenylbutadiyne is superior to that of the thermal homopolymeriza-tion.According to infrared and 1~H-NMR spectra,the structure of polymer(1) and copolymer (2) may all be trans-transoidal confignration.
