    Abstract: PROCESS FOR THE PREPARATION OF FLEXIBLE POLYURETHANE FOAMS INVOLVING THE USE OF ALIPHATIC MONOAMINES The invention relates a process for the preparation of a polyurethane foam by reacting an organic polyisocyanate, polyol, and primary or secondary aliphatic monoamine in the presence of a blowing agent and catalyst. The amines are used in quantities of 0.1 part to 10 parts by weight per 100 parts per weight of polyol. The highly elastic polyurethane flexible foams are suited for the manufacture of upholstered furniture, matresses, automobile seats and head supports, as well as particularly for molded foams. The semi-rigid polyurethane foams are used as foam backing of dashboards in automobiles, thermal and sound insulation in buildings and vehicles, and for impact absorption in packaging materials.

    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: Acylphosphine oxide compounds of the general formula where R1 is alkyl, cyclohexyl, cyclopentyl, aryl which is unsubstituted or substituted by halogen, alkyl or alkoxy, or an S-containing or N-containing five-membered or six-membered heterocyclic radical, R2 has one of the meanings of R1 (but R1 and R2 may be identical or different) or is alkoxy, aryloxy or aralkoxy, or R1 and R2 together form a ring and R3 is an at least disubstituted phenyl, pyridyl, furyl or thienyl radical which carries, at least at the two carbon atoms adjacent to the linkage point of the carbonyl group, the substituents A and B, which may be identical or different, and each of which is alkyl, alkoxy or alkylthio of 1 to 6 carbon atoms, cycloalkyl of 5 to 7 carbon atoms, phenyl or halogen, or R3 is a-naphthyl substituted by A and B at least in the 2- and 8-positions or is .beta.-naphthyl substituted by A and B at least in the 1- and 3-positions, a 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 these acylphosphine oxide compounds as photoinitiators in photopolymerizable surface coatirg?, finishes and printing inks.
