The effect of trifluromethyl group substitution on the thermal properties of blends of a polyaramide with several aliphatic polyamides has been determined. Miscibility of the substituted polyaramide with nylons 46, 6, 66, 69, 610 and 11 was shown by the existence of single, composition-dependent glass transition temperatures (Tgs) and composition-dependent crystalline melting temperatures (T=s). The results are discussed with reference to Tg and Tr~ predictive equations.
