ABSTRACT:
Unsaturated addition-polymerizable urethane resins prepared from polyester polyols based on (1) at least one glycol selected from the group consisting of 1,3-butylene glycol and neopentyl glycol; (2) adipic acid; (3) isophthalic acid; and, optionally, (4) at least one aliphatic polyhydroxy compound containing at least three hydroxy groups are characterized by reduced viscosity, improved physical stability, and by improved solubility and compatibility in organic solvents/diluents. Particularly advantageous resins are obtained by employing isocyanate-functional prepolymers based on the subject polyester polyols, with isocyanate-functional prepolymers obtained by reacting the polyester polyol compounds with organic polyisocyanate compounds at an NCO:OH ratio greater than 2:1 being especially preferred, as precursors for such unsaturated addition-polymerizable urethane resins.
