Abstract: A process for the production of mouldings having a cellular core and a compacted peripheral zone and improved demoulding properties by the polyisocyanate polyaddition process, by reacting a) organic polyisocyanates b) relatively high-molecular-weight compounds containing at least 2 reactive hydrogen atoms, and, if desired, c) low-molecular-weight polyhydric alcohols, polyoxyalkylene-polyols and/or secondary aromatic diamines in the presence of d) an internal mould release agent, comprising A) from 0.1 to 12% by weight, based on the total weight of components (b) and (c), of a mixture of i) from 5 to 80 parts by weight of at least one organic amine, and ii) from 20 to 95 parts by weight of at least one metal salt of stearic acid, and B) from 0.01 to 32% by weight, based on the total weight of components (b) and (c), of at least one organic mono- and/or dicarboxylic acid or anhydrides thereof, e) catalysts, f) blowing agents, and, if desired, g) assistants and/or additives, in a closed mould with compaction, expediently using the low-pressure or preferably reaction injection moulding technique.

Abstract: A process for the preparation of cellular plastics, preferably rigid structural polyurethane foams, by the polyisocyanate polyaddition process involves reacting a) organic and/or modified organic polyisocyanates with b) at least one relatively high-molecular-weight compound containing at least two reactive hydrogen atoms, and optionally c) low-molecular-weight chain extenders and/or crosslinking agents, in the presence of d) blowing agents from the group comprising tertiary alcohols (di), preferably tertiary butanol, or a mixture of at least one tertiary alcohol (di) and water (dii), e) catalysts and optionally f) assistants and/or additives. a
