FOAM PRODUCTS AND METHODS OF PRODUCING THE SAME

摘要

Compositions for the formation of heat resistant foams are disclosed. The invention also relates to a process for the production of polymeric foams containing amide groups with foaming substantially accomplished by elimination of carbon dioxide by reaction of polyfunctional isocyanates, carboxylic acids, and polyols in the presence of a catalyst system composition comprises a catalyst compound having a cation of a metal, in a salt or ligand, which metal is selected from the group consisting of magnesium, cobalt, manganese, yttrium, Lanthanide Series metals, and combinations thereof, resulting in formation of amide groups in the polymer.

主权项

1. A polymer foam material formed from a foamable composition comprising:
an organic polyisocyanate component; a polyacid component substantially reactive with the polyisocyanate to form an amide group in a polyamide-urethane copolymer; a polyol component substantially reactive with the polyisocyanate component to form a urethane group in a polyamide-urethane copolymer; a surfactant composition component; and a catalyst system composition having substantial catalytic activity in the curing of said foamable composition, wherein the catalyst system composition comprises a catalyst compound comprising a cation of a metal, in a salt or ligand, which metal is selected from the group consisting of magnesium, cobalt, manganese, yttrium, Lanthanide Series metals, and combinations thereof; wherein the curing reaction is associated with the elimination of carbon dioxide derived from a carboxy group in the polyacid and results in formation of amide groups in the copolymer component.
