Abstract
This invention relates to crosslinkable polymeric compositions and a process for preparing them which show a low content of vinyl monomers, are suitable for the fabrication of composite materials, have good mechanical properties, and comprise: a liquid polyisocyanate; a polyol having a maximum functionality of 7 and an average molecular weight of from about 200 to about 10,000; an unsaturated polyester or a vinylester resin; a radical polymerization initiator stable at temperatures below 70.degree. C.; a decomposition promoter for the initiator; a trimerization catalyst for the isocyanate; and optionally, a mineral filler having dehydrating properties.
