Abstract
Melt-processing a mixture of a polyphenylene ether (PPE) and an ethylenically unsaturated carboxylic compound, in the absence of an added free radical initiator such as a peroxide, serves to introduce carboxyl functionality into the PPE resin. The resulting carboxylated PPE resins are useful in forming alloys with more polar resins such as polyamides.
Claims7
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 0.5 to 1.0 pbw of an ethylenically unsaturated carboxylic compound.
An improved process for preparing carboxylated phenylene ether resins comprising 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.
