摘要： Molding compositions of thermoplastic plasticizer-containing polyamides exhibit greatly reduced migration of plasticizer or no migration at all due to having 0.1 to 20% by weight of sterically hindered carbodiimides of the formulaR.sub.1 --N.dbd.C.dbd.N--[R.sub.2 --N.dbd.C.dbd.N].sub.2 --R.sub.3wherein n is 0 to 100; R.sub.1 and R.sub.3 are individually a monovalent radical taken from the class consisting of aliphatic having 1 to 20 carbon atoms, cycloaliphatics having 6 to 20 carbon atoms, and aromatics having 8 to 20 carbon atoms and also having substituents; and R.sub.2 is a divalent radical taken from the class consisting of aliphatics having 1 to 20 carbon atoms, cycloaliphatic having 6 to 20 carbon atoms, and aromatics having 8 to 20 carbon atoms and also having substituents.
摘要翻译： 含有热塑性增塑剂的聚酰胺的成型组合物显示出大大降低了增塑剂的迁移或根本没有迁移，这归因于具有式R 1 -N = C = N- [R2-N = C = N] 2-R 3，其中n为0至100; R 1和R 3分别是从具有1至20个碳原子的脂族，具有6至20个碳原子的脂环族和具有8至20个碳原子并且也具有取代基的芳族化合物组成的一类基团; R2是从具有1至20个碳原子的脂族基团，具有6至20个碳原子的脂环族基团和具有8至20个碳原子并具有取代基的芳烃取代的二价基团。

摘要： Thermoplastic polyamide molding materials containing impact resistance-providing additives, which are reinforced with glass fibers and are colored with dyes and pigments, comprise a mixture of components A and B.Component A comprises glass fiber-containing polyamide and component B comprises polyamide with impact resistance-providing additives and can also contain dyes, pigments, heat and light-stabilizers, as well as processing agents.Due to the separate addition of the glass fibers and the impact resistance-providing additives, pigments, etc. to the polyamide, the conventional reduction in mechanical properties, such as impact resistance and notch toughness, on the addition of all the other components to the polyamide, is surprisingly prevented.

摘要： Cold impact-resistant tubing especially useful as a fuel line for motor vehicles which is stable in length, has a brief thermal overload capacity, and consists of at least three layers of at least two different mutually compatible polyamides. The tubing also preferably has an internal and an external layer of impact resistance-modified polyamide, with or without a plasticizer, and a barrier between the layers of impact resistance modifier-free homopolyamide, copolyamide or blends thereof.

摘要： An article consisting of a base and one or more attachments thereto. The base is made of one thermoplastic polymer and the attachment is made of a second thermoplastic polymer which is at least partially incompatible with the first polymer. Either the first or second polymer contains 5 to 75% by weight of a third polymer which is an olefinic polymer having functional groups thereon. Either of the first two polymers may contain up to 90% of the usual additives. This enables the production of such articles with high interface strength.
