Abstract: The invention relates to a method for the production of polyether alcohols from oxiran compounds in the presence of at least one multi-metal cyanide catalyst and a moderator gas selected from the group containing carbon dioxide, carbon monoxide, hydrogen and dinitrogen oxide or various mixtures of said gases at pressures of at least 1 bar, in addition to polyether alcohols obtained according to said method.

Abstract: The invention relates to a method for the homogeneous catalytic production, starting from ethene, of highly branched amorphous polyolefins which have an elastomeric characteristic profile. In a first step of said method a) ethene is oligomerized in the presence of a transition metal compound of general formula (I), whereby R and R represent C4 to C16 heteroaryl or C6 to C16 aryl with hydrogen substituents in both vicinal or ortho positions in relation to the binding site between the aryl or heteroaryl and N or N and is optionally oligomerized in the presence of a co-catalyst in an inert solvent. In a further step b), a transition metal compound of general formula (II) is added to the oligomerization mixture produced according to step a) and the reaction is continued in the presence of ethene. In a subsequent step c), the polymer product obtained is isolated.

Abstract: A process for the production of polyolefin nano-composites involves the transition metal-catalysed polymerisation of 2-20C alk-1-enes or vinyl-aromatic compounds in presence of a dispersion of layered silicate(s). An Independent claim is also included for polyolefin nano-composites obtained by this process.
