ABSTRACT:
A polysulfide-modified epoxy resin system in which, upon curing, the polysulfide rubber phase separates into discrete particles, typically 1 to 5 .mu.m in size, to enhance physical properties such as peel strength without any significant reduction in glass transition temperature. The phase separation is brought about by using as a modifier a liquid polysulfide containing a high proportion of polymethylene groups of 4 to 12 carbon atoms. The polysulfide may be adducted with an excess of epoxy resin prior to incorporation in the composition.
