【摘要】 研究了不同共混比的氯化聚乙烯(CM)/乙烯-醋酸乙烯酯(EVM)共混胶的物理机械性能、两相溶胀度及两相交联密度;并研究了共混胶中CM相和EVM相产生相间交联的特征、动态力学性能、CM硫化胶与乙酸乙酯溶剂的相互作用参数及EVM硫化胶与丁酮溶剂的相互作用参数。结果表明,当m(CM)/m(EVM)=30/70时,共混胶的拉伸强度较大;共混胶中CM相与EVM相的交联密度比较匹配;两相间有相间交联。更多还原

【Abstract】 In this paper,the physical and mechanical properties of chlorincated polythylene(CM)/ethylene-vingl acetate resin(EVM) blends at different ratios,degree of swelling of the two phases and two phases crosslink density of CM/EVM blends,characteristics of cross-linking between CM phase and EVM phase and the dynamic mechanical properties of CM/EVM blends were studied.In addition,vulcanizated CM rubber with ethyl acetate solvent interaction parameter and vulcanizated EVM rubber with butanone interaction parameters were konwn.The results showed that when m(CM)/m(EVM)=30/70,the tensile strength of the rubber blends was better than others,CM phase and EVM phase crosslink density matched with each other.It had been found that there were cross-linking between the two phases.更多还原
