Abstract
A composition comprising a polymeric resin derived from (A) at least one compound containing an average of more than one 1-oxa-3-aza-tetraline group per molecule with (B) at least one cycloaliphatic epoxide containing at least two epoxide groups, at least one of said epoxide groups being part of said ring, the mole ratio of (b) to (a) .Iadd.epoxide groups to 1-oxa-3-aza-tetraline groups .Iaddend.being in the range of about 0.2 to about 2.
