Abstract
Liquid epoxy resins can be converted to non-sintering, relatively low equivalent weight, flakable solid opoxides having relatively low melt viscosities by advancing the resins with 1,1,1-tri(hydroxyphenyl)alkanes or -alkenes in which the alkane or alkene moiety contains from 1 to 11 carbons.
