    • PURPOSE: Inner parting agents for producing self-parting mouldings made of polyisocyanate polyaddition products are provided, which are stable in storage and can produce large size compact or cellular mouldings capable of containing reinforcing agents. CONSTITUTION: Self-parting, compact or cellular mouldings made of polyisocyanate polyaddition products, if required containing reinforcing agents, are provided by reacting (a) organic and/or modified organic polyisocyanates with (b) at least one compound with at least two reactive hydrogen atoms and a molecular weight from 62 to 10,000; and optionally (c) chain lengthening and/or cross-linking agents, in the presence of (d)inner parting agents, and in the presence or absence of (e) catalysts; (f)foaming agents; (g) reinforcing agents and (h) additives, in an open or closed moulding tool. The process is characterized in that alkylsuccinic acid esters and/or semi-esters and/or alkenylsuccinic acid esters and/or semi-esters are used as inner parting agents (d).
