IPN用乳液聚合方法合成了聚甲基丙烯酸甲酯和聚丙烯酸丁酯的互穿聚合物网络(IPN).动态力学分析结果表明:这种半相容的PMMA/PnBA乳胶IPN在-50°～+60℃温度范围内具有良好的阻尼性能,组成和交联剂用量影响该体系的相容性和阻尼性能.李树材天津科技大学材料科学与化学工程学院李允明...
Transmission electron microscopy images proved that in the ternary system the two diblock copolymers formed no own separate phase but are arranged as a ring layer at the interface between the two homopolymers PMMA and PnBA. Charpy tests demonstrated that the impact strength of the ternary blends ...
