Abstract
The invention relates to a polyphenylene ether resin containing residual aliphatic unsaturation as well as composites, blends, and articles made from the polyphenylene ether resin containing residual aliphatic unsaturation. Also included are reaction products between the polyphenylene ether resin containing residual aliphatic unsaturation and other resins and unsaturated resin formulations, e.g., thermosetting polyesters, acrylics, bismaleiimides, silicones, and allylics, and thermoplastics such as polyolefins, styrenics, rubbers, etc.
