Abstract

The invention relates to a process for the production of mouldings having a compact outer layer and a cellular core, for example soft, flexible shoe soles, having a density of from 0.4 to 1.0 g/cm<3>, by reacting a) organic and/or modified organic polyisocyanates with b) at least one high-molecular-weight compound containing at least two reactive hydrogen atoms and, if desired, c) low-molecular-weight chain extenders and/or crosslinking agents, in the presence of d) low-boiling aliphatic and/or cycloaliphatic hydrocarbons having 4 to 8 carbon atoms in the molecule, preferably pentanes, as blowing agent, e) catalysts and, if desired, f) assistants and/or additives. l
