聚丙烯酸酯类材料的阻尼性能研究

Study on the damping property of the polyacrylic ester materials

摘要: 本文合成组成相同的聚丙烯酸酯类IPN聚合物、线性IPN聚合物、共聚物、共混物,通过示差扫描量热仪(DSC)、动态粘弹谱(DMA)等实验方法比较它们的阻尼性能;结果表明聚丙烯酸酯类IPN聚合物具有更佳的阻尼性能,其原因是IPN聚合物组份之间的协同作用而使其相容性表现为接近分子水平的共混.

Abstract: This paper has synthesised the polyacrylic ester IPN polymer,the linear IPN polymer,the copolymer and the blend of the same components and compared their damping properties by the experimental methods including Different Scanning Calorimetry(DSC)and Dynamic Mechanical Analysis(DMA);the polyacrylic ester IPN polymer has better damping property because IPN polymer components show the synergies effect and make its blend compatibility near molecule level.
