Abstract
Abstract Polyhydroxyethers formed by reacting a diglycidyl ether of biphenol, such as diglycidyl ethers of bisphenol-A, and a dihydroxybiphenyl, such as dihydroxybiphenyl, tetramethyldihydroxybiphenyl, and tetrabromotetramethyldi- hydroxybiphenyl, exhibit high heat distortion temperatures. These compositions could find utility in extruded films, packaging and coatings.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
40 words
A polyhydroxyether composition comprising a reaction product of a diglycidyl ether of a biphenol with a dihydroxybiphenyl, in which the repeating unit of the polyhydroxyether contains at least an oxyhydrocarbon connecting group and a hydrocarbon or halogen substituted phenylene radical.
Claim 2
Dependent Claim
40 words
A polyhydroxyether composition comprising a reaction product of a diglycidyl ether of a biphenol with a dihydroxybiphenyl, in which the repeating unit of the polyhydroxyether contains at least an oxyhydrocarbon connecting group and a hydrocarbon or halogen substituted phenylene radical.
Claim 3
Dependent Claim
53 words
The polyhydroxyether of Claim.1 wherein the polyhydroxyether has the general repeating unit wherein R is selected from the group consisting of hydrogen, methyl radicals, halogen radicals selected from the group consisting of chlorine and bromine radicals, and mixtures thereof, A is a hydrocarbon radical, and n has a value of zero to 1.
Claim 4
Dependent Claim
41 words
The polyhydroxyether of Claim 1 wherein the diglycidyl ether of a biphenol is selected from the group consisting of wherein X is selected from the group consisting of the hydrogen, chlorine, and bromine radicals, and mixtures thereof, and and mixtures thereof.
Claim 5
Dependent Claim
24 words
The polyhydroxyether of Claim 1 wherein the dihydroxybiphenyl is selected from the group consisting of an unsubstituted dihydroxybiphenyl, tetramethyldihydroxybiphenyl, brominated tetramethyldihydroxybiphenyl, and mixtures thereof.
Claim 6
Dependent Claim
39 words
A composition as defined in Claim 4 wherein the repeating unit of the polyhydroxyether is selected from the group consisting of wherein X is selected from the group consisting of the hydrogen, chlorine and bromine radicals, and mixtures thereof.
Claim 7
Dependent Claim
71 words
A polyhydroxyether composition of Claim 1 comprising a reaction product of a diglycidyl ether of a biphenol selected from the group consisting of wherein X is selected from the group consisting of the hydrogen, chlorine, and bromine radicals, and mixtures thereof, and and mixtures thereof, with a dihydroxybiphenyl, in which the repeating unit of the polyhydroxyether contains at least an oxyhydrocarbon connecting group and a hydrocarbon or halogen substituted phenylene radical.
Claim 8
Dependent Claim
