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.

Claims

1. A composition comprising a polyphenylene ether resin of the formula:

wherein R¹ is an aliphatic or aromatic residue;

n is 0 to about 10;

each of R² R³, and R⁴ is independently hydrogen, alkyl, or aryl;

j has an average value less than 49;

each Q¹ is independently halogen, primary or secondary lower alkyl, phenyl, haloalkyl, aminoalkyl, hydrocarbonoxy, or halohydrocarbonoxy wherein at least two carbon atoms separate the halogen and oxygen atoms; and

each Q² is independently hydrogen, halogen, primary or secondary lower alkyl, phenyl, haloalkyl, hydrocarbonoxy or halohydrocarbonoxy wherein at least two carbon atoms separate the halogen and oxygen atoms.

2. The composition of claim 1, wherein j has an average value less than 34.

3. The composition of claim 1, wherein n is zero.

4. The composition of claim 1, wherein R² is methyl or hydrogen, R³ is hydrogen, and R⁴ is hydrogen.
