【摘要】 本文报道了以α-氯代萘为溶剂的聚氯化磷腈的溶液聚合方法,合成了标题高聚物。测定了它的红外和核磁谱,GPC法估计其数均分子量为5×10~5,扭辫分析表明该聚合物的玻璃化转变与粘流温度分别为13℃和170℃。更多还原

【Abstract】 Poly(p-phenylphenoxy/Ethoxy substituted phosphazene) polymer was synthesized by the reaction of poly (diehlorophosphazene), which was prepared by solution polymerization in solvent α-chloronaphthalene, with p-phenylphenolate and ethoxide(3 : 1). The obtained polymer was characterized by IR, H-NMR, GPC and TBA. The results show that the number average molecular weight M_n reachs the leveal of 5×10~5. And The temperatures of glass transition and viscous flow respectively are 13 ℃ and 170 ℃.更多还原
