摘要： A moldable reinforced polyamide composition comprising (a) a polyamide consisting essentially of between about 0.5 and about 99.5 mol. % of aliphatic diamines having 4-12 carbon atoms and a complementary amount of 2-methyl-pentamethylene diamine copolymerized with aliphatic dicarboxylic acids having 6-12 carbon atoms; and (b) a filler in an amount of 0.5 to 200 parts by weight per 100 parts by weight of said polyamide. The polyamide has an RV greater than about 20. Related polyamides, especially in which the acid is 1,12-dodecanedioic acid, are also disclosed. The polyamides may be used in a wide variety of end-uses, including moulding, and exhibit excellent gloss compared with nylon 6,6.
摘要翻译：一种可模制增强聚酰胺组合物，其包含（a）基本上由约0.5至约99.5摩尔组成的聚酰胺。％的具有4-12个碳原子的脂肪族二胺和与具有6-12个碳原子的脂族二羧酸共聚的2-甲基 - 戊二胺的互补量; 和（b）相对于100重量份所述聚酰胺为0.5〜200重量份的填料。聚酰胺的RV大于约20.相关聚酰胺，特别是其中酸是1,12-十二烷二酸，也被公开。聚酰胺可以用于各种最终用途，包括模塑，并且与尼龙6,6相比表现出优异的光泽度。
