ABSTRACT:
Salts generally act as reinforcing compounds in polyurethane compositions. Salts containing a free-amine function generally increase the low-strain moduli more than salts which lack such free-amine functions or are neutral. The salts are generally formed by reacting a basic nitrogen function compound such as a monoamine or a diamine with a mono or a dicarboxylic acid.
