Abstract

Time-temperature dependence of concentrations of outgasing products of polymers and rubbers was studied. Applying the principle of time-temperature equilibrium, the exposure time for a laboratory rapid study of polymers at 100 degrees C was estimated to be 1 hr for enamels, lacquers and dyes, 1.5 hr for block and sheet polymers, 2.5 hr for sealants and rubbers, and 4 hr for textile materials, measured from the time when the preassigned temperature was achieved. The rapid method can be recommended for preliminary chemical study of polymers at the stage of their laboratory testing.

摘要

研究了聚合物和橡胶脱气产物浓度的时间-温度依赖性。应用时间-温度等效原理,对于在100℃下对聚合物进行实验室快速研究的暴露时间,从达到预定温度时开始计算,瓷漆、清漆和染料为1小时,块状和片状聚合物为1.5小时,密封剂和橡胶为2.5小时,纺织材料为4小时。该快速方法可推荐用于聚合物在实验室测试阶段的初步化学研究。
