具有高结晶度的部分芳香族共聚酰胺成型材料

Partly aromatic copolyamide molding materials having high crystallinity
摘要：
Partly aromatic semicrystalline thermoplastic polyamide molding compositions contain A) from 40 to 100% by weight of a copolyamide composed of a.sub.1) from 30 to 44 mol % of units which are derived from terephthalic acid, a.sub.2) from 6 to 20 mol % of units which are derived from isophthalic acid, a.sub.3) from 43 to 49.5 mol % of units which are derived from hexamethylenediamine and a.sub.4) from 0.5 to 7 mol % of units which are derived from aliphatic cyclic diamines of 6 to 30 carbon atoms, the molar percentages of components a.sub.1) to a.sub.4) together giving 100%, and B) from 0 to 50% by weight of a fibrous or particulate filler, C) from 0 to 30% by weight of an elastomeric polymer and D) from 0 to 30% by weight of conventional additives and processing assistants, the percentages by weight of components A) to D) together giving 100%.
