【摘要】 本工作合成了环氧树脂/蓖麻油聚氨酯互穿网络高聚物(IPN)。研究了这个IPN体系的力学性能和热性能随组分比和氰羟比的变化。在一个IPN体系中得到了两组具有协同效应的组分比。发现两网间轻微交联有利于体系性能的提高。更多还原

【Abstract】 Epoxy/Polyureathane based on castor oil interpene-trating polymer networks are synthesized. Themechanical and thermal properties of the IPN systemare studied. Two synergic points are found in theIPN system. It is found that slight graft betweentwo networks are helpful to the improvement ofIPN’s properties.更多还原
