摘要

在羟基/异氰酸酯基官能团比4∶1的条件下

通过超支化聚合物Boltorn H20（HPE）与Upy（ureidopyrimidinone）的反应

合成了带有四重氢键单元的改性超支化聚合物HPE-1.采用核磁共振仪及红外分析仪测定了HPE-1的结构.由于分子间强的相互作用

HPE-1在熔融状态下可拉丝

而HPE不能.由于分子中含有亲水的羟基和疏水的Upy基元

HPE-1在水中能够自组装成球状聚集体.在酸性溶液中聚集体变大

而在碱性溶液中聚集体破坏

这为制备敏感性材料提供了途径.

Abstract

A hyperbranched polymer(HPE-1)with quadruple hydrogen bonding units was prepared through reacting Boltorn H20(HPE)with ureidopyrimidinone(Upy)at hydroxyl and isocyanate group ratio of 4∶1.The structure of HPE-1 was characterized by 1H-NMR and IR.The melting HPE-1 can form long fibers under pulling due to the strong interaction of the molecules

but HPE can’t.With both hydrophilic hydroxyl groups and hydrophobic Upy units

HPE-1 self-assembled into spherical aggregates in water.The aggregate become larger in acidic solutions

but dissociate under basic conditions

which provides a way for preparing sensitive material.
