用同步预聚合法合成了聚丙烯酸丁酯/蓖麻油聚氨酯半(SEN),通过拉伸试验、TBA和SEM等手段对其性能和形态进行了表征.结果表明,在一定组分比下半SEN的力学性能协同增加.该半SEN为部份相容体系,具有两相结构,相区尺寸约8000um左右.讨论了形态对性能的影响.
Poly (butylacrylate) / castor oil polyurethane semi (SEN) was synthesized by simultaneous prepolymerization and its properties and morphology were characterized by means of tensile test, TBA and SEM.The results showed that under certain conditions, The semi-SEN is a partially compatible system with a two-phase structure and the size of the phase region is about 8000um.The effect of morphology on the performance is discussed.
