【摘要】 本文对聚氨酯/聚苯乙烯互穿聚合物网络(IPN)的热稳定性进行了系统研究,通过改变PU/PS组份比及不同交联剂用量,观察体系的热分解趋势,发现热稳定性随网络化学构型及交联密度的变化明显变化,同时对其热分解机理进行讨论。更多还原

【Abstract】 The heat stability of PU/PS IPN was systematically investigated. The heat decomposition tendency of the system was observed with the Change of the ratio of PU/PS components and the volume of various crosslinking agents. It was found that the heat stability was obviously changed with the chemical configuration and crosslinking density. Meanwhile, the mechanism of heat decomposition was discussed.更多还原
