| 摘 要： | 采用同步法合成的丁腈羟聚氨酯/聚甲基丙烯酸酯类IPN样品,以TPA动态力学方法研究它的丙烯酸酯组份中,不同组份比,侧基结构和含量与动态力学性能的关系。结果指出,这些体系是半相容体系和相容体系。包含甲基丙烯酸正丁酯,异丁酯的IPN力学阻尼峰比甲基丙烯酸甲酸所具有的峰明显加宽。IPN中丙烯腈对体系的动态力学影响较大。

| Abstract: | IPNs from PU(HTBN) and Polymethacrylates were synthesized by simultaneous crosslinking polymerization. The relationship between the dynamical properties of IPNs and the ratio of two components,the side groups and their contents in polymethacrylate networks were studied by means of torsional pendulum analysis.The results showed that the IPNs are semicompatible or compatible.Some more widened peaks were found in Δ-T plots of IPNs containing poly(n-BMA) and poly (iso-BMA) than of those containing poly (MMA). Acrylonitrile component was shown more affecting on the dynamic mechanical properties of IPNs obtained. |
