摘要：
The present invention relates to the production in closed molds, of foams with outstanding mold-release properties. These improved properties are obtained by including in the foamable mixture salts of saturated or unsaturated aliphatic or cycloaliphatic carboxylic acids having at least 8 carbon atoms and tertiary amines of the type in which the atom ratio of tertiary amine nitrogen to carbon in the molecule is between 1:3 and 1:12.
