尼龙增韧剂是马来酸酐接枝聚烯烃弹性体(POE)，该产品残留单体含量少，凝胶含量低，具有高反应活性。由于在非极性的分子链上引入了强极性的侧基，马来酸酐接枝POE可以成为增进极性材料与非极性材料粘接性和相容性的桥梁。 尼龙增韧剂用于PA6、PA66耐高温加纤增韧等，提高尼龙的抗冲击性、耐寒性、成型加工性、降低吸水率。改性后的尼龙具有高强度、高机械模数、低潜变性，主要应用于汽车、电气设备、机械部构；交通器材、纺织、造纸机械等。

Nylon toughening agent is maleic anhydride grafted polyolefin elastomer (POE), which has low residual monomer content, low gel content and high reactivity. The grafting of maleic anhydride on POE can be a bridge to enhance the adhesion and compatibility of polar and nonpolar materials because of the introduction of the strong polarity side group on the nonpolar molecular chain. Nylon toughening agent for PA6, PA66 high temperature and fiber toughening, improve nylon impact resistance, cold resistance, molding processing, reduce water absorption. The modified nylon has high strength, high mechanical modulus and low latent denaturation. It is mainly used in automobile, electrical equipment, mechanical structure, transportation equipment, textile, paper making machinery and so on.
