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.

Cross-linkable polyester/isocyanate compositions suited for the

Copolyesters having an improved combination of barrier, mechanical, thermal and rheological properties and consisting of acylic and glycolic radicals, wherein the acylic radicals derive from at least isophthalic acid and 2,6-naphthalene dicarboxylic acid and at least 90% by mols of the glycolic radicals derive from ethylene glycol.
