【摘要】 研究毛细管挤出过程中PVC与轻度交联MBS共混物熔体的胀大行为及其影响因素.结果表明:温度和剪切应力对挤出胀大比B值的影响较大;B与口模长径比及MBS用量成反比关系.从理论上分析了PVC/MBS共混体系的微观相作用.更多还原

【Abstract】 The die swell behavior of PVC/MBS blend melt in capillary extrusion was studied It has been found that the effect of temperature and shear stress on the die swell ratio(\%B\%) is evident, the relationship between \%B\% and the die length\|diameter ratio, MBS content was proximately inverse proportion The microphase structure of PVC/MBS blends was analyzed theoretically更多还原
