Abstract
The present invention provides trimerization catalyst compositions and methods to produce a polyisocyanurate/polyurethane foam using such trimerization catalyst compositions. The catalyst composition is the contact product of at least one α,β-unsaturated carboxylate salt and at least one second carboxylate salt.
Claims29
A catalyst composition comprising the contact product of
- (a) at least one α,β-unsaturated carboxylate salt having the formula:
- wherein X, Y, and Z are selected independently from a C1-C36 alkyl, alkenyl, aryl, or aralkyl, any of which are substituted or unsubstituted;
- —CO2H;
- —CO2M1;
- or a hydrogen atom;
- and
- wherein M1 in each occurrence is selected independently from:
- (i) an alkali metal ion,
- (ii) an alkaline earth metal ion, or
- (iii) a quaternary ammonium ion;
- and
- (b) at least one second carboxylate salt.
9 more elements
A catalyst composition comprising the contact product of
- (a) at least one a,6-unsaturated carboxylate salt;
- and
- (b) at least one second carboxylate salt selected from:
- (i) an alkali metal carboxylate salt,
- (ii) an alkaline earth metal carboxylate salt,
- (iii) a quaternary ammonium carboxylate salt, or any combination thereof.
