Abstract

The production of foamed synthetic resins from mono-, di- or tri-methylol ketones directly according to the parent Specification, or via the precondensates of Specification 1,031,579, is modified by the addition before foaming of at least one organic liquid boiling at 40-130 DEG C. Preferred liquids are aliphatic, cycloaliphatic or aromatic hydrocarbons, halohydrocarbons or mixtures thereof, added in amounts of 3-7% of the total reaction mixture. Preferred starting material is an acetone methylol compound, and polyglycols and higher alcohols may also be included in the reaction mixture.
