  • Patent number: 6210523
    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 C2-C20 starter polyol and optional additives. These compositions are useful as binders for the production of composite materials.
