In the organic amine salt compound having the following general formula (I), A n- [B m+ ] p (I) where A n- is the -n valent anion as a CO 2 donor, n=1,2 or 3, B m + is or comprises an ammonium ion, a hydrazine ion and/or an organic amine B cation, m=1-10, 0<p= is, A n- is (a) a carbazic acid ion or carbazic acid ion: R 1 R 2 N-COO - or R 1 R 2 N-NH-COO - ; (b) carbonate ions; (c) formate ions; (d) hydrogen carbonate ions; (e) organic monocarbonate ions; (f) organic polycarbamic acid ions; (g) orthoformate ions; or (h) one or several types selected from organic polycarbonate ions, The compound of the general formula (I) has at least one hydroxyalkyl group bonded to an N atom, in other words, it contains an alcohol amine compound residue. They are used as polyurethane blowing agents, and most blowing agents are used as polystyrene blowing agents or polyvinyl chloride blowing agents. |
