| titleOfInvention | Process for the preparation of adducts containing epoxy groups from polyepoxy compounds and N-heterocyclic compounds |
| abstract | 'Advanced' adducts contng. epoxy grps., made by heating together (i) an N-heterocyclic cpd. where Z = divalent residue, free from N atoms, giving an opt. subst. 5- or 6-membered ring, and (ii) a polyepoxy cpd. (II) pref. contng. an average of 2-3 epoxy grps., using 1 equiv. (pref. 0.02-0.5, esp. 0.06-0.3 equiv.) NH in (I) per 1 equiv. epoxy grp. in (II). Examples of specific cpds. (II) are diglycidyl ethers of biphenols, e.g. diglycidyl ether of 2,2-bis(p-hydroxyphenyl)propane; cycloaliphatic polyepoxy cpds. Cpds. (I) may be e.g. hydantoin derivs:- such as 5,5-dimethylhydantoin or 5-isopropylhydantoin. Cured products have excellent electrical properties, esp. resistance to tracking. |
