Abstract

Compositions made up of an aromatic polyisocyanate and a polyester having an average molecular weight of from about 600 to about 5000, obtainable by self-condensation of ricinoleic acid, optionally with co-utilization of a C.sub.2 -C.sub.20 starter polyol and optional additives. These compositions are useful as binders for the production of composite materials.
