| 摘 要： | 通过熔融共混法制备了PC/HBPS共混物,研究了其流变特性。结果表明,此共混物属于假塑性流体,随着HBPS含量的增加,非牛顿指数增加;随着剪切速率的增加,表观黏度下降,但下降趋势较缓慢;随着温度的增加,表观黏度下降,但下降趋势很快;共混物的粘流活化能都比纯PC的粘流活化能高;随着HBPS含量的增加,表观黏度下降。

| Abstract: | Rheological characteristics of polycarbonate and highly branched polystyrene(PC/HBPS-1) blends prepared by melt blending were studied.Results show that the PC/HBPS-1 blends belong to the pseudo-plastic liquids.The non-Newtonian index of the PC/HBPS-1 blends is increased with the increase of HBPS-1 content.The apparent viscosity of the PC/HBPS-1 blends is decreased with the increase of shear rate and temperature,at the same time,the decreased trend of shear rate is slow and that of temperature is soon.The viscous activation energy of the PC/HBPS-1 blends is higher than that of pure PC.The apparent viscosity of the PC/HBPS-1 blends is decreased with the increase of HBPS-1 content. |
