Abstract
Disclosed in an alicyclic end-capping agent for a heterocyclic compound, which is represented by the formula [I]: ##STR1## wherein X is CO, O, S, CH.sub.2 or substituted CH.sub.2, Y.sub.1 -Y.sub.6 are halo, H, NO.sub.2, aryl, alkaryl, arylalkyl or alkyl ether, and Z is ##STR2## (Q.sub.1 is --NH.sub.2, --SH, --OH or ##STR3## (Q.sub.2 is H, or monovalent aliphatic or amomatic group). Also disclosed is an addition-curable quinoxaline resin oligomer having the above-mentioned alicylic end-capping agents at both terminals of oligomer. This oligomer is useful especially for an intermediate material for a fiber-reinforced composite.
Claims7
An end-capping agent for a heat-resistant heterocyclic compound, which has an alicyclic structure and imide structure represented by the following general formula [I]:
- ##STR21## wherein X represents CO, O, S, CH.sub.2, a halogen substituted methylene group, an alkyl-substituted methylene group having 1 to 6 carbon atoms in the alkyl group or an aryl-substituted methylene group, Y.sub.1 through Y.sub.6 independently represent a halogen atom, H, NO.sub.2, an aryl group, an alkaryl group having 1 to 6 carbon atoms in the alkyl group, an arylalkyl group having 1 to 6 carbon atoms in the alkyl group or an alkyl ether group having 1 to 6 carbon atoms in the alkyl group, and Z.sub.1 represents ##STR22## (in which Q.sub.1 represents --NH.sub.2, --SH, --OH or ##STR23## in which Q.sub.2 represents H, a monovalent aliphatic group or a monovalent aromatic group.
