Title:
METHOD FOR PRODUCING A LIQUID POLYMER COMPOSITION AND THE USE OF THIS COMPOSITION
Document Type and Number:
WIPO Patent Application WO2001040317
Kind Code:
A3
Abstract:
The invention relates to a method for producing a liquid polymer composition, whereby ethylenically unsaturated monomers are polymerized using initiators, which have a transferable atom group, and using one or more catalysts, which comprise(s) at least one transition metal. This polymerization is carried out in the presence of ligands, which can form a coordination compound with the metallic catalyst(s). In addition, the catalyst is oxidized after polymerization, and the catalyst is then separated out by filtering. The composition has a solvent with a dielectric constant less than or equal to 4.
