| 摘 要： | 本文研究了聚氨酯(PU)-聚乙烯醇(PVA)共混体系的动态力学性质、相逆转现象和透气性能.发现当PVA重量含量为30-50％时,共混体系发生了连续相与分散相的逆转.进一步,通过力学模型描述了该共混体系的模量-组成关系、动态力学温度谱以及透气系数与PVA含量的关系曲线.所有实验数据都落在理论预测的范围内,并分别与改进的Kerner模型和组合Kerner模型相符合.

| Abstract: | In this paper, the dynamic mechanical property and the phase inversion of the polyurethane (PU)-polyvinyl(PVA) blend system were studied. It was found that the phase inversion bet-ween the contious phase and the disperse phase took place when PVA content reached the range of 30-50%. Furthermore, mechanical models were used to describe the modulus composition relation, the isochronal mechanical spetrum and the diffusion coefficient composion relation of the blends. The experiment data were within the theoretic prediction and respectively fitted the modified Kerner model and combination Kerner model. |
