    摘要： A thermoplastic polyamide comprising a copolyamide and a modified copolyolefin. The copolyamide is the reaction product of a hexamethylene diamine, which may be substituted with one or more alkyl groups, and a his (4-aminocyclohexyl) alkane which is substituted adjacent to the amino groups, and a dicarboxylic acid.Molded bodies made therefrom have high rigidity, excellent impact resistance over a broad temperature range, low water uptake, high dimensional stability, low permeability to oxygen, and high shape retention on heating. They are particularly suitable for injection molding and extrusion, especially for the preparation of thin walled or large surface area shapes.

    摘要： Transparent copolyamides with very good processibility, very good mechanical properties, excellent transparency and hydrolysis stability in boiling water, and alloyability with other polyamides, are obtained through polycondensation of alkyl derivatives of dicycane and additional polyamide-forming components, together with isophthalic acid and an .omega.-aminocarboxylic acid or its lactam with more than 8 C-atoms, or salts thereof, or a stoichiometric mixture of an aliphatic dicarboxylic acid and an aliphatic diamine.The copolyamides of the invention are excellently suitable for the production of molded articles, thanks to their low processing viscosity.

    摘要： Highly viscous or heat distortion-resistant at least partially crosslinked polyamides are disclosed along with the process for making them. The process comprises reacting, under anhydrous conditions, a polyamide melt with a silane of the following formula ##STR1## wherein n=0, 1, or 2,Z is individually an organic radical which may, together with other Z groups and the silicon atom, form rings,A is individually a moisture hydrolyzable radical which may, together with other A groups and the silicon atom, form rings, andY is an organic radical containing a functional group which is capable of reacting with at least one of an amide, amino and carboxyl group of the polyamide to form a covalent bond,and then bringing the reaction product into contact with moisture to form the at least partially crosslinked polyamides.
