| 摘 要： | 以季戊四醇为"核",与1,2,4-偏苯三酸酐和环氧氯丙烷反应合成超支化聚合物,并通过马来酸酐进行端基改性,合成了以羟基和/或羧基为末端基的水溶性超支化聚合物(HBPs),通过FT-IR1、H-NMR对结构进行了表征。然后将该超支化聚合物(HBPs)应用于BA/VAc/AA丙烯酸共聚物压敏胶粘剂(PSAs)乳液中。发现超支化聚合物的加入提高了胶粘剂的稳定性和粘接性能。以羧基为末端基的超支化聚合物(HBP-B)加入量为0.5%时,胶粘剂互相矛盾的两个性能——持粘力与剥离强度同时达到最大值。

| Abstract: | A series of hyperbranched polymers(HBPs) were synthesized and measured by FT-IR and 1H-NMR.Two types of HBPs with-COOH and-COOH/-OH as end-groups were used to modify the performance of BA/VAc/AA emulsion-based pressure-sensitive adhesives(PSAs).The influences of the HBPs on the properties of PSAs were discussed.It is found that both the stability and the adhesive properties of PSAs are improved by HBPs.Further more,0.5% HBP as the modifier with-COOH as end groups increase shear strength and peel strength to... |
