摘要
基于非共价相互作用形成的超分子聚合物具有许多特殊的性能,它主要包括配位聚合物、π–π堆积聚合物和氢键结合聚合物3类。具有脲基嘧啶酮(Upy)四重氢键识别基元的超支化聚合物显示了优良的涂层性能,并且随着温度升高,熔体黏度迅速降低,这类聚合物适合用作热熔型涂层材料。
Supramolecular polymers which are formed via non-covalent bonding possess many unique properties. Up to date, three main categories of non-covalent bonding, including coordination, n-stacking and hydrogen bonding, have been used in assembling such polymers. It was found that hyperbranched polymers bearing ureidopyrimidone (Upy) units display good coating performances due to the formation of self-complementary quadruple hydrogen bonding of Upy units. Their melt viscosities are decreased sharply with increasing temperature, which makes the polymers suitable for use as novel hot-melting coating materials.
