Abstract
This invention relates to liquid, hydrophobic, non-migrating, non-functional polyurethane plasticizers. These plasticizers comprise the reaction product of an isocyanate-terminated prepolymer and a monofunctional alcohol having a molecular weight of about 32 to about 1,000. The isocyanate-terminated prepolymers comprise the reaction product of a diisocyanate and at least one hydrophobic polyol. The present invention also relates to a process for the production of the liquid, hydrophobic, non-migrating, non-functional polyurethane plasticizers. This invention also relates to a process for the production of a polyurethane product comprising reacting at least one polyisocyanate component with at least one isocyanate-reactive component, in the presence of these liquid, hydrophobic, non-migrating, non-functional polyurethane plasticizers, and to the resultant polyurethane products of this process.
