Abstract:
The invention provides polyurethane and polyisocyanurate foams and methods for the preparation thereof. More particularly, the invention relates to polyurethane and polyisocyanurate foams having an open-cell, closed-cell or a combination of open and closed cell structure, and methods for their preparation. The foams are produced with a polyol premix composition which comprises a combination of a hydrohaloolefin blowing agent, a polyol and a catalyst which is an adduct of an amine and an organic acid.

Claim (Index 12):
A method of forming an aged polyol premix composition which comprises:\n forming a polyol premix by combining (a) from about 1 wt % to about 30 wt % of_a blowing agent, (b) from about 60 wt. % to about 95 wt. % of a polyol, (c) from about 0.5 wt. % to about 5.0 wt. % of a silicone surfactant, and (d) from about 0.2 wt. % to about 8.0 wt. % of_a catalyst which catalyst is an adduct of a tertiary amine and an organic acid, wherein the blowing agent comprises (i) from about 10 wt % to about 70 wt % of a hydrohaloolefin based on the weight of the blowing agent, wherein said hydrohaloolefin is selected from the group consisting of trans-1,3,3,3-tetrafluoropropene, trans-1-chloro-3,3,3-trifluoropropene, and combinations thereof, and (ii) an auxiliary blowing agent selected from the group consisting of hydrocarbon, fluorocarbon, chlorocarbon, fluorochlorocarbon, halogenated hydrocarbon,_ethers, esters, aldehydes, ketones, halogenated ethers, CO 2  generating material, or combinations thereof, and storing said premix after said formation, such that foam formed from the polyol premix compositon exhibits substantially no cell collapse after said premix has been aged at 120\u00b0 F. for 62 hours.
