METHOD FOR MANUFACTURING COPOLYMER CONSISTING OF CARBON MONOXIDE AND OLEFINICALLY UNSATURATED COMPOUND IN AQUEOUS MEDIUM, AQUEOUS COPOLYMER SYSTEM THUS MANUFACTURED AND ITS USAGE

摘要

PROBLEM TO BE SOLVED: To improve a method for catalytically manufacturing a copolymer consisting of carbon monoxide and a 2-20C olefinically unsaturated compound in an aqueous medium by using a metal catalyst system. SOLUTION: In order to obtain a copolymer consisting of carbon monoxide and a 2-20C olefinically unsaturated compound, the copolymerization of carbon monoxide and the olefinically unsaturated compound is carried out in an aqueous medium in the presence of (a1) a metal complex of the general formula (I) (wherein, the substituents and the factors are shown in the specification), (b) a dispersant, and (c) optionally, an organic hydroxy compound. The copolymerization is carried out in the presence of a water-soluble high molecular host compound having hydrophobic hollow sections and hydrophilic outer coats.
