A series of soy bean oil-based polyols were synthesized by treating either the oil or epoxidized soybean oil by variety of reagents including borontrifluoride and long chain fatty acids. The products were fully characterized and were then chain extended with excess diisocyanate compounds to produce stable prepolymers. The NCO-terminated polymers were then capped with a variety of aminosilane coupling agents to yield isocyanate-free moisture curing polymers. These polymers were then formulated into both clear coat and pigmented ambient curing coatings.
