Title:
STRENGTH-IMPROVING AGENT FOR PRODUCTION OF POLYURETHANE FOAM
Document Type and Number:
WIPO Patent Application WO/2011/105028
Kind Code:
A1
Abstract:
Provided is a strength-improving agent for the production of polyurethane foam, said agent enabling the production of a polyurethane foam having high tensile strength, tear strength and compression strength. A strength-improving agent (A) for the production of polyurethane foam, represented by general formula (I) [wherein each R1 is a residue derived from an active-hydrogen containing compound by the removal of one active hydrogen atom, and multiple R1s may be the same or different; Y is a residue derived from an at least trivalent aromatic polycarboxylic acid (C) by the removal of the carboxyl groups; the aromatic ring of Y is composed of carbon atoms; the substituents on the aromatic ring may be hydrogen or other groups, with the proviso that at least one of the substituents is hydrogen; a is an integer satisfying the relationship: 2 < a < [(the number of substituents on the aromatic ring) - 2]; Z is a residue derived from an at least m-valent active-hydrogen containing compound by the removal of m active hydrogen atoms; some R1s and Z may be the same, with the proviso that at least one R1 is different from Z; and m is an integer of 1 to 10].
