Zusammenfassung:PCT No. PCT/GB89/00477 Sec. 371 Date Nov. 2, 1990 Sec. 102(e) Date Nov. 2, 1990 PCT Filed May 5, 1989 PCT Pub. No. WO89/10948 PCT Pub. Date Nov. 16, 1989.A polymeric composition comprises: (i) an aromatic polyimide or an aromatic carboxylic ester polymer, (ii) a substantially wholly aliphatic polyamide, and (iii) a polyamide that contains both aromatic aliphatic moieties. It is found that the mechanical properties of blends of the aromatic polymers (i) and the polyamides (iii) can be significantly improved by the incorporation of a quantity of the aliphatic amides (ii), even though the miscibility of polymers, as observed by their glass transition temperatures may remain unchanged.
