众所周知,受阻胺光稳定剂对聚烯烃有良好的光稳定效率,已引起世界的注意。然而,小分子量的受阻胺易于挥发,从而影响它的效率发挥,为了克服这个缺点,使小分子受阻胺的高分子化是近年来受阻胺光稳定剂发展的方向,本文主要是研究三种商品化高分子受阻胺光稳定剂对聚丙烯的稳定化作用及其效率和机理。 It is well known that hindered amine light stabilizers have a good light-stabilizing efficiency for polyolefins and have attracted worldwide attention. However, the low molecular weight hindered amine easily volatilized, thus affecting its efficiency to play. In order to overcome this shortcoming, the molecularization of small molecule hindered amines is the development direction of hindered amine light stabilizers in recent years. This article mainly studies three kinds of commodities Stabilization Effect of Polymeric Hindered Amine Light Stabilizer on Polypropylene and Its Efficiency and Mechanism.
