Polyurethane foams with excellent physical properties are obtained by using a catalyst composition of a tertiary amine and 2-ethylhexanoic acid.

Catalyst for making polyurethanes

New ditertiary aminoalcohols are useful as catalysts in the preparation of polyurethane foams. The new catalysts are particularly stable in the presence of polyols and other components often used in the conjunction with such polyols.

N'-(2-Hydroxyalkyl)-N, N, N'-trimethyl-propylene diamines as catalysts

Polyurethane foams with excellent physical properties can be obtained by using a partial salt between N,N-dimethylaminopropane-1,3-diamine (DMAPA) and a branched octanoic acid.

Polyurethane foams with excellent physical properties can be obtained by using a partial salt between N,N-dimethylaminopropane-1,3-diamine (DMAPA) and phenol.

Blends of polycarbonates with from 3 to about 10 weight per cent of a graft polymer having incorporated therein pendent phenalkyl groups exhibit markedly decreased notch sensitivity. The blends have remarkably high clarity and low haze.
