  The present invention relates to a polyamide composition comprising polyamide, polyketone, and rubber, wherein the polyketone is present in an amount of no more than 5 wt%, based on the total weight of the polyamide composition. The inventive polyamide composition has and exhibits improved mechanical properties and chemical resistance both to Zinc salt and glycol, and thus is particularly useful in the manufacture of articles for automotive application.

  本发明涉及一种聚酰胺组合物，包括聚酰胺、聚酮和橡胶，其中聚酮的含量不超过聚酰胺组合物总重量的 5%。本发明的聚酰胺组合物具有并显示出更好的机械性能和对锌盐和乙二醇的耐化学性，因此特别适用于制造汽车用品。

  The present invention provides polyamide compositions comprising (a) at least one polyamide mixture; (b) at least one reinforcing filler; (c) at least one heat stabilizer; and (d) at least one ionic lubricant, wherein the (a) at least one polyamide mixture is formed from (i) a polyamide 6,6, the amount of AEG being greater than the amount of CEG, and (ii) a blend of a first high chain-length polyamide having viscosity number (VN) of X1 and a second high chain-length polyamide having VN of X2, X1 being greater than X2. The polyamide composition can be advantageously used to produce articles exhibiting enhanced chemical resistance, notably CaCl2 salt crack resistance, such as radiator end tank in an automobile.

  本发明提供了聚酰胺组合物，其包括：(a) 至少一种聚酰胺混合物；(b) 至少一种增强填料；(c) 至少一种热稳定剂；(d) 至少一种离子润滑剂；(d) 至少一种离子润滑剂，其中(a)至少一种聚酰胺混合物由(i)聚酰胺 6,6（AEG 的含量大于 CEG 的含量）和(ii)第一种高链长聚酰胺（粘度值（VN）为 X1）与第二种高链长聚酰胺（粘度值（VN）为 X2）的混合物（X1 大于 X2）形成。这种聚酰胺组合物可以很好地用于生产具有更强耐化学性的物品，特别是耐 CaCl2 盐裂纹的物品，例如汽车的散热器末端水箱。
