Abstract
Compositions comprising a carboxylated PPE resin and a polyamide having good compatibility and impact properties. The carboxylated PPE resin/polyamide alloys are produced by a process wherein a mixture consisting essentially of the PPE resin and a minor amount of an unsaturated carboxylic compound are first melt processed, then compounded with the polyamide.
Claims8
A composition comprising from 25 to 95 wt % of a polyamide and, correspondingly, from 75 to 5 wt % of a carboxylated phenylene ether resin, said carboxylated resin being the product of melt-mixing a mixture consisting essentially of 100 parts by weight phenylene ether resin and from 0.05 to 1.0 pbw of an ethylenically unsaturated carboxylic acid compound.
An improved process for preparing blends of polyamides and phenylene ether resins comprising the steps of
- a. melt-mixing a mixture consisting essentially of 100 parts by weight of phenylene ether resin and from 0.05 to 1.0 pbw of an ethylenically unsaturated carboxylic compound to provide a carboxylated phenylene ether resin;
- and
- b. further melt processing said carboxylated phenylene ether resin in the presence of polyamide.
