摘要
烷基取代哌啶胺化合物与三聚氯氰分步缩合反应合成中间体 6-氯 -2 ,4 -双 ( N ,N -( 2 ,2 ,6 ,6 -四甲基 -4 -哌啶基 -烷基 )胺基 ) -1 ,3,5 -三嗪 ,此中间体再与烷基多胺如乙二胺、二乙烯三胺等缩合得到一系列单体型高分子量哌啶三嗪类化合物 ;制备了对叔丁基杯 [4 ]芳烃、高分子受阻胺类化合物和聚丙烯共混体系 .通过老化性能实验评价了共混体系的抗热氧性能 ,结果表明 ,杯芳烃和受阻胺类复合稳定剂能明显提高聚丙烯的耐热氧性能 。
chloro 2,4 di( N,N (2,2,6,6 tertamethyl 4 piperidyl alkyl amine) 1,3,5 triazine has been synthesized from alkylated piperidineamine and cyanuric chloride by condensation reaction, then condensed with alkyl polyamine such as ethylenediamine, diethylenetriamine et al to give a series of high molecular weight piperidine triazine compounds. A polypropylene blend with p tert butyl calixarene and high molecular weight hindered amine compound was prepared, and their thermal oxidation stability were evaluated. The blend exhibited an excellent antithermal oxidative performance due to the synergistic effects.
