| 摘 要： | 本文用(Ph_3P)_2PdCl_2为催化剂,合成了1,4-丁炔二醇(BD)与4,4-二乙炔联苯(DEBP)共聚物。对用不同比例的两种单体得到的共聚物测定了比重(d_4~(25)、溶胀度(θ_D)、最良溶剂及相邻两交联点之间的平均分子量(M_c)。实验表明,在两种单体摩尔比中,DEBP用量越多,共聚物中泡状微孔越多,颜色越淡,溶胀度和比重越小,交联度越大;DEBP/BD(摩尔比)大于1/5时,共聚物的最良溶剂为苯,溶度参数为9.15卡~(0.5)·cm~(-1.5),是1/10时,其最良溶剂为乙醇,溶度参数是12.7卡~0.5·cm~(-1.5)。对共聚物还做了红外光谱表征。

| Abstract: | The copolymers of 1,4-butynediol (BD) and 4, 4'-diethynylbiphenyl (DEBP) in different ratios are first synthesized using (Ph3P)2PdCl2 as catalyst. The density, the swellability and the average molecular weights between crosslinks of all copolymers are measured. As the mole ratio of DEBP/BD is larger than 1/5, the best solvent of copolymers is benzene, but as that is 1/10, the beat solvent is ethyl alcohol, the. IR spectra of all copolymers are done, too. |
