A method for preparing compression molded or pressed lignocellulosic articles is disclosed. The method involves forming a binder resin by combining a polyisocyanate component with a parting agent and preferably a synergist. The parting agent is the reaction product of an isocyanate compound and an isocyanate-reactive compound of the general structure R&mdash;(ao) &mdash;Y where: R is a hydrophobic group containing alkyl, alkaryl, polyaryl, or siloxane moieties; (ao) is an alkylene oxide or mixture of alkylene oxides; n is from 1 to 25; and Y represents a monofunctional isocyanate-reactive group. A resinated lignocellulosic mixture is formed by combining the binder resin with lignocellulosic particles. Then a compression molded or pressed lignocellulosic article is formed by compressing the resinated lignocellulosic mixture at an elevated temperature and under pressure. It is particularly preferred that the binder resin further include a synergist of either a C N-alkylpyrrolidone, gamma-butyrolactone, or a mixtures of them. The most preferred synergist is N-methyl-2-pyrrolidine.

A polyester polyol composition comprising a phthalic anhydride-initiated polyester polyol, a C -C hydrocarbon blowing agent, and an alkylene oxide modified silicone glycol compatibilizing agent having an HLB of from about 5 to about 8 is disclosed. The blowing agent is soluble in the polyol composition, thereby reducing the risks associated with such blowing agents in processes for making rigid polymer foam articles and providing rigid foams having good dimensional stability and improved insulation properties. An alkylene oxide and isocyanate modified silicone glycol compatibilizing agent is also disclosed.
