Abstract

Disclosed are methods and compositions for preparing rigid foams by contacting a polyisocyanate with a polyol mixture comprising (a) from about 40-95% by weight of a polyester or polyether polyol; (b) a catalytic amount of a catalyst system comprising a primary catalyst and an amino acid salt catalyst derived from sarcosine; and (c) a non-chlorofluorocarbon blowing agent.
