Abstract
Abstract Functionalized polyphenylene ether compositions are provided which are particularly useful for effecting compatibility for a blend of polyphenylene ether resin and a polyamide resin. The functionalized-polyphenylene ether is the reaction product of a polyphenylene ether polymer and a compound having the general formula (i)-Z-(ii), wherein group (i) is a polyphenylene ether-philic moiety such as acyl chloride, group (ii) is a polyamide-philic moiety such as dicarboxylic acid anhydride, and Z is a divalent hydrocarbon radical providing a covalent linkage between groups (i) and (ii). An example of the compound having general formula (i)-Z-(ii) is trimellitic anhydride acid chloride.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
73 words
A functionalized-polyphenylene ether compound comprised of the reaction product of a polyphenylene ether polymer and a compound having the general formula (i)-Z-(ii) that contains both group (i) which is at least one polyphenylene ether-philic acylfunctionalized moiety; and group (ii) which is at least one polyamide-philic moiety; and wherein Z is a divalent hydrocarbon radical linking groups (i) and (ii), provided that groups (i) and (ii) are not both the simultaneously carboxylic acid groups.
Claim 2
Dependent Claim
73 words
A functionalized-polyphenylene ether compound comprised of the reaction product of a polyphenylene ether polymer and a compound having the general formula (i)-Z-(ii) that contains both group (i) which is at least one polyphenylene ether-philic acylfunctionalized moiety; and group (ii) which is at least one polyamide-philic moiety; and wherein Z is a divalent hydrocarbon radical linking groups (i) and (ii), provided that groups (i) and (ii) are not both the simultaneously carboxylic acid groups.
Claim 3
Dependent Claim
27 words
A composition as in claim 1 wherein said polyphenylene ether polymer is selected from the groups consisting of poly(2,6-dimethyl-1,4-phenylene) ether and copolymers of (2,6-dimethyl-1,4-phenylene) and (2,3,6-trimethyl-1,4-phenylene) ethers.
Claim 4
Dependent Claim
