Abstract: Aqueous hydrophobic polyurethane dispersions are made from urethane prepolymers derived from reacting constituents including at least one polyisocyanate, vegetable oil based saturated monoglycerides, non-isocyanate based urethane polyols prepared from polyamines and cyclic carbonates, at least one long-chain polymeric polyol or long-chain polyol from biorenewable resources, polyols with hydrophilic groups, optional polydimethysiloxane based polyols with hydroxyl functional groups terminated in one end and alkyl groups terminated in another end.

Abstract: A seed-oil based reactive diluent is synthesized via a two-step process wherein in the first step, unsaturated seed oils such as soybean oil first react with mono-hydroxy functional amines to form an intermediate mixture composed of mono-hydroxy functional seed oil based derivatives and in the second step, a core molecule having multiple hydroxyl-reactive groups reacts with the intermediate mixture prepared from the first step and a polyol cross-linker to form a reactive diluent with a star-branched shape.
