  • Patent number: 5859285
    Abstract: Disclosed is a carbamate adduct prepared by contacting carbon dioxide with an alkanolamine, preferably in a polar medium. The alkanolamine is characterized in that it consists of 1 or 2 ether linkages per molecule. The adduct finds value as a thermally decomposable blowing agent when preparing polyurethane foam and elastomeric products. Integral-skinned polyurethane products prepared in the presence of the carbamate adducts disclosed herein exhibit an enhanced abrasion resistance.
    Type: Grant
