Abstract

The features of the production process of polymeric foams based on polyvinyl chloride and reactive isocyanates in the presence of carboxylic acid anhydrides as crosslinking agents are investigated. The infl uence of the nature of isocyanates and their concentration on the formation of imide fragments in the polymer matrix, on the physical-mechanical and temperature-deformation properties of foams is shown. The glass transition temperatures of the obtained materials are determined.
基于聚氯乙烯和反应性异氰酸酯的含亚胺聚合物泡沫
研究了在羧酸酐为交联剂的情况下,以聚氯乙烯和活性异氰酸酯为原料制备泡沫聚合物的工艺特点。研究了异氰酸酯的性质及其浓度对聚合物基体中亚胺碎片的形成、泡沫的物理力学和温度变形性能的影响。测定所得材料的玻璃化转变温度。
