【摘要】 本文在合成SBS树脂的基础上,研究了SBS及SBS-EVA共混体系的力学性能随组成和温度的变化规律。一定组成的共混物可用作“刚柔兼顾”的医用导管材料。从动态力学温度谱和透射电镜观察研究了共混体系的微相分离结构。更多还原

【Abstract】 Based on the synthesis of SBS res-ins, the mechanical properties of SBSand SBS/EVA blends and their relat-ions to compositions and temperaturewere studied. Blends of certain comp-ositions may be used as medical vesselmaterials of both hard and flexiblecharacters.It was also found that thetorsional rigidity was very insensitiveto temperature changes. And the mic-roseparation and domain structure ofthe system were investigated by DDVand TEM.更多还原
