摘要
本文用热重法测定了芳基乙炔均聚物及其与苯乙炔的共聚物的热分解温度和成碳率,所得结论有:共聚物中含二乙炔芳烃量越多,交联度越大,则其热分解温度越高,成碳率也越大;二乙炔芳烃和苯乙炔共聚物的成碳率远高于按其均聚物计算所得的成碳率。
The thermal degradation temperatures and the rate of char yields ofhomopolymers and coplymers of arylacetylenes were determined by thermogr-avimetry.The correlations between these properties and the composition andstructure of polyarylacetylenes were also revealed.The more diethynylaromaticcopolymer contains and the bigger cross link density,the higher the thermaldegradation temperature and char yields.Char yields of copolymer ofdiethynylaromatic and phenylacetylene are much greater than that of thecalculated data from their homopolymers.
