Abstract
The present invention relates to curable polyurethane polymers made from renewable materials and having polymerization accelerator groups built into the polymer. In particular hydroxylated oleaginous materials derived from plant oils, such as soybean oil, are used. These renewable materials may be formed into curable polyurethane polymers having different chemical functionalities and cure mechanisms.
Claims8
