Claims Analysis

Total Claims: 19
Claim 1
Independent Claim 232 words
A curable composition comprising linear molecules which are the polymeric reaction product of (1) a bis-naphthol with a diglycidyl ether of a bis-phenol in the presence of base, or (2) a diglycidyl ether of a bis-naphthol with a bis-phenol in the presence of base, each of (1) and (2) with or without crosslinking and wherein the bis-naphthol has the formula ##STR20## wherein X 1 and X 2 each independently is an alkyl group containing from 1 to 4 carbon atoms or a halogen atom having an atomic number of from 9 to 35, inclusive; M is 0, 1 or 2; n is 0, 1, 2, 3 or 4; and A is a divalent hydrocarbon radical selected from the group consisting of an alkylene group containing from 3 to 8 carbon atoms, or a divalent radical derived from a non-aromatic carbocyclic or a dialkyl carbocyclic aromatic or dialkyl non-aromatic carbocyclic group containing from 7 to 24 carbon atoms in which each alkyl group contains from 1-8 carbon atoms and the carbocyclic group comprises (a) a central non-aromatic carbocyclic ring containing 5 to 7 carbon atoms in a ring or (b) a central aromatic carbocyclic ring wherein the central ring of (a) or (b) may be bridged or fused with one or two non-aromatic or aromatic carbocyclic rings, and wherein the naphthol is directly attached to the alkyl substituent of the dialkyl carbocyclic group.
Claim 2
Dependent Claim 232 words
A curable composition comprising linear molecules which are the polymeric reaction product of (1) a bis-naphthol with a diglycidyl ether of a bis-phenol in the presence of base, or (2) a diglycidyl ether of a bis-naphthol with a bis-phenol in the presence of base, each of (1) and (2) with or without crosslinking and wherein the bis-naphthol has the formula ##STR20## wherein X 1 and X 2 each independently is an alkyl group containing from 1 to 4 carbon atoms or a halogen atom having an atomic number of from 9 to 35, inclusive; M is 0, 1 or 2; n is 0, 1, 2, 3 or 4; and A is a divalent hydrocarbon radical selected from the group consisting of an alkylene group containing from 3 to 8 carbon atoms, or a divalent radical derived from a non-aromatic carbocyclic or a dialkyl carbocyclic aromatic or dialkyl non-aromatic carbocyclic group containing from 7 to 24 carbon atoms in which each alkyl group contains from 1-8 carbon atoms and the carbocyclic group comprises (a) a central non-aromatic carbocyclic ring containing 5 to 7 carbon atoms in a ring or (b) a central aromatic carbocyclic ring wherein the central ring of (a) or (b) may be bridged or fused with one or two non-aromatic or aromatic carbocyclic rings, and wherein the naphthol is directly attached to the alkyl substituent of the dialkyl carbocyclic group.

Claim 8
Dependent Claim 43 words
A composition according to claim 5 of a diglycidyl ether of a bis-naphthol wherein A is a divalent radical derived from a dialkylaromatic carbocyclic group containing 12 to 20 carbon atoms in which each alkyl group contains from 3 to 5 carbon atoms.
Claim 9
Dependent Claim 11 words
A composition according to claim 7 which includes a bis-phenol component.
Claim 10
Dependent Claim 11 words
