摘要
采用溶液缩聚法合成了苯乙烯-马来酸酐共聚物接枝聚对羟基苯甲酸侧链液晶高分子,讨论了反应的接枝率和液晶侧链对高聚物热性质的影响。
The liquid crystalline copolymers of styrene - maleic anhydride grafted by p - hydroxy benzoic acid(HBA) were synthesized through condensation polymerization in pyridine solvent at mild temperature. The copolymers were characterized by means of Fourier transform infrared spectrometry (IR.), differential scanning calorimetry (DSC) . It was found that the temperature of glass transition rose because of the introduction of liquid crystalline side chains.
