    Abstract: The invention is concerned with an acylphosphine oxide of the formula (I) (I) where R1 is straight-chain or branched alkyl of 1 to 6 carbon atoms, cyclohexyl, cyclopentyl, phenyl, or naphthyl which are unsubstituted or substituted by halogen, alkyl of 1 to 6 carbon atoms or alkoxy of 1 to 6 carbon atoms, or a S-containing or Ncontaining five-membered or six-membered aromatic heterocyclic radical having one heteroatom; R2 has one of the meaning of R1, but R1 and R2 may be identical or different, or is alkoxy of 1 to 6 carbon atoms, phenoxy, methylphenoxy, benzyloxy or vinyloxy, or R1 and R2 may be joined together to form an acylphosphonic acid o-phenylene ester; and R3 is straight-chain or branched alkyl of 2 to 18 carbon atoms, an .alpha.-acyloxyethyl . .beta.-carboxyethyl radical, a cycloaliphatic radical of 3 to 12 carbon atoms, a vinyl, a methylvinyl, a naphthyl radical, a phenyl or naphthyl which are substituted by an alkyl of 1 to 8 carbon atoms or by thioalkoxy of 1 to 6 carbon atoms, a phenyl or naphthyl which are substituted by an alkoxy of 1 to 6 carbon atoms, or a S-containing or Ncontaining five-membered or six-membered aromatic heterocyclic radical having one heteroatom,or is the group: whera R1 and R2 have the above meanings and X is phenylene or an aliphatic or cycloaliphatic divalent radical of 2 to 6 carbon atoms, with the proviso that R1 and R2 do not simultaneously stand for alkyl of 1 to 6 carbon atoms if R3 is an alkoxy substituted phenyl and with the further proviso that R1 is not t-butyl or benzyl if R3 stands for t-butyl or n-butyl. This invention also concerned the process for the preparation of these acylphosphine oxide compounds from acid halides of the general formula where X is chlorine or bromine, and a phosphine of the general formula and the use of the acylphosphine oxides as photoinitiators in photopolymerizable compositions.

    Abstract: The invention relates to a process for preparing self-releasing, compact or cellular moulded bodies optionally containing reinforcing agents and made of polyisocyanate polyaddition products 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 of 500 to 9,000 and optionally c) chain extension and/or cross-linking agents in the presence of d) alkyl and/or alkenyl succinic acid monoamides, -monoamides, poly(alkyl succinic acid)- and/or poly(alkenyl succinic acid)-polyamides, -polyimides, -monoamide monoimides, -polyamide imides, -amide polyimides and- polyamide polyimides or mixtures thereof as internal mould release agents, and also in the presence or absence of e) catalysts, f) blowing agents, g) reinforcing agents, h) auxiliary agents, in an open or closed moulding tool, optionally under compression. The invention also relates to the use of alkyl- and/or alkenyl succinic acid amides and/or imides (d) as internal mould release agents for the preparation of moulded bodies made of polyisocyanate polyaddition products.
