FIELD: polymerization catalysts.
SUBSTANCE: catalyst is composed of double metal cyanide compound, organic ligand, and two complexing components other than precedent organic ligand and selected from group including: polyethers and polyesters, glycidyl ethers, esters from carboxylic acids and polyatomic alcohols, bile acids, bile acid salts, bile acid esters, bile acid amides, and phosphorus compounds, provided that selected complexing components belong to different classes.
EFFECT: substantially increased catalytic activity.
