Abstract

Se describen métodos y se proporcionan composiciones para formar un catalizador. En un aspecto, el catalizador se forma al mezclar por lo menos una amina terciaria con por lo menos un ácido polimérico. Tales catalizadores son particularmente útiles en la polimerización de espumas de poliuretano.
