Abstract
Abstract Solid compositions are prepared by reacting (A) one or more materials containing an average of more than one 1,2-epoxy groups with (B) one or more materials containing an average of more than one phenolic hydroxy groups wherein at least one of (A) or (B) contains with respect to (B) or has been prepared from with respect to (A) a reaction product of (1) at least one aromatic compound having at least one aromatic ring, at least one aromatic hydroxyl group and which aromatic ring contains at least one ortho or para position which is capable of being alkylated and (2) at least one aliphatic or cycloaliphatic C 4 -C 6 unsaturated hydrocarbon or a dimer, codimer, oligomer or cooligomer thereof.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
140 words
Solid compositions resulting from reacting, in the presence of an effective quantity of a suitable catalyst, (I) at least one material having an average of more than one 1,2-epoxy group per molecule with (II) at least one material having an average of more than one phenolic hydroxyl group per molecule; wherein at least one of (I) or (II) contains with respect to (II) or has been prepared from with respect to (I) a reaction product of (A) at least one aromatic compound containing (1) at least one aromatic ring, (2) at least one aromatic hydroxyl group and (3) which aromatic ring has at least one ortho or para position capable of being alkylated, and (B) at least one unsaturated aliphatic or cycloaliphahtic hydrocarbon containing 4 to 6 carbon atoms or one or more dimers or oligomers thereof, or mixtures thereof.
Claim 2
Dependent Claim
140 words
Solid compositions resulting from reacting, in the presence of an effective quantity of a suitable catalyst, (I) at least one material having an average of more than one 1,2-epoxy group per molecule with (II) at least one material having an average of more than one phenolic hydroxyl group per molecule; wherein at least one of (I) or (II) contains with respect to (II) or has been prepared from with respect to (I) a reaction product of (A) at least one aromatic compound containing (1) at least one aromatic ring, (2) at least one aromatic hydroxyl group and (3) which aromatic ring has at least one ortho or para position capable of being alkylated, and (B) at least one unsaturated aliphatic or cycloaliphahtic hydrocarbon containing 4 to 6 carbon atoms or one or more dimers or oligomers thereof, or mixtures thereof.
Claim 3
Dependent Claim
157 words
A composition of claim 1 wherein component (I) contains an epoxy resin composition resulting from the dehydrohalogenation of the reaction product of (A) an epoxy alkyl halide; with (B) an acid catalyzed product resulting from reacting (1) at least one aromatic hydroxyl-containing compound having at least one aromatic ring and at least one ortho or para position with respect to a hydroxyl group available for ring alkylation; with (2) at least one unsaturated hydrocarbon selected from (a) unsaturated hydrocarbons having from 4 to 6 carbon atoms; or (b) dimers, codimers, oligomers or cooligimers of unsaturated hydrocarbons, which hydrocarbons have 4 to 6 carbon atoms; and wherein the components (B-1) and (B-2) are employed in quantities which provide a mole ratio of (B-1) to (B-2) of from about 1.8:1 to about 30:1, and components (A) and (B) are employed in quantities which provide an epoxy group to phenolic hydroxyl group ratio of from about 1.5:1 to about 20:1.
