Abstract
A polymeric composition comprises: PA0 (i) an aromatic polyimide or an aromatic carboxylic ester polymer, PA0 (ii) a substantially wholly aliphatic polyamide, and PA0 (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.
