摘要
功地合成了带烷端基的酚酞聚芳醚腈 ,测定其 1H- NMR谱 ,根据链中芳环质子共振峰与链端基质子共振峰积分强度比求解分子量 ,与聚合物特性粘度关联 ,确定了酚酞聚芳醚腈在四氢呋喃溶剂中 ,6 0℃的 Mark- Houwink常数 K=1.6 4× 10 -6,α=0 .918,建立了其在四氢呋喃溶剂中的特性粘度与数均分子量的关系 :[η]=1.6 4× 10 -6M0 .
A series of phenolphthalein poly(cyanoarylether) with p (t tutyl)phenol were successfully synthesized. The number average molecular weight of phenolphthalein poly(cyanoarylether.) was determinated by 1H NMR technique. Combined with [η] , relationship between [η] and number average molecular weight was estabilished. The phenolphthalein poly(cyanoarylether) in tetrahydrofuran at 60 ℃ were done to determine Mark Houwink constants. The values of K = 1.64 ×10 -6 and α = 0.918 are obtained.
