摘要

Composition of epoxy resin varnish curable laminates, process for preparing a composition of varnish for laminate of epoxy resin curable, process to prepare a laminate, laminate and prepreg.The present invention relates to a composition of a curable epoxy laminate comprising (a) an epoxy resin; (b) a block copolymer containing at least one segment of anfifu00edlico block miscible with epoxy resin and at least one segment of the block immiscible with epoxy resin; and The segment of immiscible block comprises at least a structure of polyether with the exception that the structure D.And the said Polyether Segment of immiscible block containing at least one or more units of alkylene oxide having at least four carbon atoms; in such a way that when the composition of epoxy resin is cured, the tenacity of the composition of epoxy resin cured is increased; (c ) a curing agent; and (d) a curing catalyst.The block copolymer anfifu00edlico is preferably a block copolymer, entirely of pelt as a block copolymer of peo - PbO or a copolymer in dibloco peo - PbO peo.
