Abstract
The present disclosure relates to a method for making a non-isocyanate polyurethane (NIPU) foam, where the method includes decomposing a blowing agent having at least one of an amine carbamate salt and/or an amine bicarbonate salt to form a diamine and CO.sub.2 in the presence of a molecule comprising a plurality of cyclic carbonate functional groups and reacting the diamine with at least a portion of the cyclic carbonate functional groups to form the NIPU foam. In some embodiments of the present disclosure, the reacting and the decomposing may occur at substantially the same rate.
