Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 104 words
A composition of matter comprising a combination of A. a polyphenylene ether molecule and B. compounds which contain in the molecule both (i) at least one group having the formula ##STR18## where X is F, Cl, Br, I, OH, ##STR19## where R is H or an alkyl or aryl radical and (ii) at least one carboxylic acid, acid anhydride, acid amide, imido, carboxylic acid ester, amino or hydroxyl group; wherein groups (i) and (ii) are covalently bonded through an alkyl or aryl linkage; and wherein the molecule containing groups (i) and (ii) is covalently bonded via said x group to said polyphenylene ether molecule.
Claim 2
Dependent Claim 104 words
A composition of matter comprising a combination of A. a polyphenylene ether molecule and B. compounds which contain in the molecule both (i) at least one group having the formula ##STR18## where X is F, Cl, Br, I, OH, ##STR19## where R is H or an alkyl or aryl radical and (ii) at least one carboxylic acid, acid anhydride, acid amide, imido, carboxylic acid ester, amino or hydroxyl group; wherein groups (i) and (ii) are covalently bonded through an alkyl or aryl linkage; and wherein the molecule containing groups (i) and (ii) is covalently bonded via said x group to said polyphenylene ether molecule.
Claim 3
Dependent Claim 48 words
A composition as in claim 1 wherein the composition (c) is produced by reaction of polyphenylene ether with a molecule containing groups (i) and (ii) and the composition contains between 0.1 and 6 weight percent of the molecule containing groups (i) and (ii) covalently bonded to polyphenylene ether.
Claim 4
Dependent Claim 18 words
A composition as in claim 1 wherein said composition is precompounded or prereacted with said polyphenylene ether resin.
Claim 5
Dependent Claim 103 words
A composition as in claim 1 wherein said polyphenylene ether is a homopolymer or copolymer having units with the repeating structural formula: ##STR20## wherein the oxygen ether atom of one unit is connected to the benzene nucleus of the next joining unit, and n is a positive integer of at least 50, and each Q is, independently, a monovalent substituent selected from a group consisting of hydrogen, halogen, hydrocarbon and hydrocarbonoxy groups free of a tertiary alpha-carbon atom, and halohydrocarbon and halohydrocarbonoxy groups free of a tertiary alpha-carbon and having at least 2 carbon atoms between the halogen atom and the phenyl nucleus.
Claim 6
Dependent Claim 14 words
A composition as in claim 4 wherein said polyphenylene ether is primarily poly(2,6-dimethyl-1,4, phenylene)ether.
Claim 7
Dependent Claim 27 words
A composition as in claim 1 further comprising a polyamide selected from the group consisting of polyamide 6; polyamide 6/6; polyamide 4/6; polyamide 12 and polyamide 6/10.
Claim 8
Dependent Claim 23 words
A composition as in claim 8 wherein said polyamide is selected from the group consisting of polyamide 6/6, polyamide 6 or combinations thereof.
Claim 9
Dependent Claim 43 words
A composition as in claim 1 wherein the composition is a reaction product of a first compound selected from the group consisting of chloroformylsuccinic anhydride, chloroethanoylsuccinic anhydride, trimellitic anhydride acid chloride, 1-acetoxy acetyl-3,4-dibenzoicacid anhydride, and terephthalic acid acid chloride, reacted with polyphenylene ether.
Claim 10
Dependent Claim 21 words
A composition as in claim 1 wherein the composition is a reaction product of trimellitic anhydride acid chloride and polyphenylene ether.
