| 摘 要： | 综述了铸型（MC）聚酰胺在增强、增韧改性方面的研究进展。通过加入增韧剂、共聚或改变助催化剂结构可大幅度提高MC聚酰胺的冲击性能，但往往带来拉伸性能的下降；在MC聚酰胺中加入无机填料或纤维可达到改善拉伸性能的目的，但其韧性变差。而采用分子复合和纳米复合技术可得到刚柔兼备、综合性能全面提高的新型MC聚酰胺。

| Abstract: | Advances in the reinforcement and toughening of MC polyamide are reviewed. Introducing tonghener, copolymerization, or using proper catalyst may improve the impact strength, but reduced the tensile strength. On the other hand, the inclusion of inorganic particles or fibrous filler may increase the tensile strength at the cost of toughness. However, the approaches of molecular compositing and nanocompositing may result in enhancement in both tensile strength and toughness. |
