Polyol compositions for polyurethanes
First Claim
1. A method of forming a resin composition for forming a polyurethane resin, comprising:
- preparing a polyol composition comprising;
reacting together;
(a) a triglyceride of a C12 to C25 hydroxy-substituted fatty acid; and
(b) calcium hydroxide to hydrolyze the triglyceride to yield a fatty acid in free form and glycerol; and
saponifying the fatty acid to give a fatty acid salt, the calcium hydroxide being provided in an amount of at least 0.1 mole per mole of the triglyceride; and
combining the polyol composition with a polyisocyanate to form the resin composition.

Abstract
A polyol composition for reacting with a polyisocyanate to form a polyurethane resin, comprises: (a) a triglyceride of a C12 to C25 hydroxy-substituted fatty acid or a C12 to C25 hydroxy-substituted fatty acid and glycerol, which can react together to produce a triglyceride; and (b) at least 0.1 mole per mole of triglyceride (a) or triglyceride capable of being formed from the fatty acid and the glycerol, of an oxide, hydroxide, or carbonate of a metal from Group IIA of the periodic table. A composition for reacting with a polyisocyanate to form a polyurethane resin, comprises the reaction products of: (a) a triglyceride of a C12 to C25 hydroxy-substituted fatty acid, a C12to C25 hydroxy-substituted fatty acid and glycerol, which can react together to produce a triglyceride: and (b) at least 0.1 mole, per mole of triglyceride (a) or triglyceride capable of being formed from the fatty acid and the glycerol, of an oxide, hydroxide or carbonate of a metal from Group IIA of the periodic table.
