Abstract

La presente invención se refiere a un proceso para producir una espuma de poliuretano celular o microcelular en donde los reactivos proporcionan una capacidad integrada de soplado, el proceso está caracterizado porque se hace reaccionar un poliisocianato con un poliol modificado por carboxi para formar un producto de poliuretano u otro derivado de isocianato y dióxido de carbono, el dióxido de carbono actúa como un agente de soplado in situ para formar el poliuretano en una espuma celular o microcelular.
