POROUS POLYURETHANE OBJECT

摘要

A porous polyurethane object having interconnected micropores which has been obtained with a polyamine compound as the only crosslinking agent. The porous polyurethane object is obtained by polymerizing a polyol, a chain extender, a hydrophilic chain extender, and an isocyanate, crossliking the resultant aqueous dispersion of an isocyanate-terminated urethane propolymer with a polyamine compound, and removing water from the resultant gel.
