FIELD: chemistry.

SUBSTANCE: present invention relates to a process for the preparation of a polyurethane material. Said method comprises preparation of at least one isocyanate, preparation of at least one isocyanate-active component, reparation of a catalyst composition and mixing and reacting said components to produce a polyurethane material. Isocyanate-active component is selected from monools or polyols having an average nominal hydroxyl functionality of 1-8 and an average molecular weight of 32-8000. Catalytic composition includes metal-containing polyhedral oligomeric silsesquioxane compounds that are products of the reaction of metal alkoxides and silsesquioxane silanols corresponding to the structure [2]

,

where R is selected from an alkyl group, preferably a linear, branched or cyclic aliphatic group, preferably containing from 1 to 20 carbon atoms. Ratio of the number of equivalents of silsesquioxane silanols to the number of equivalents of metal alkoxides ranges from 1.5:1 to 2:1.

EFFECT: catalytic metal-containing silsesquioxane compounds used have good solubility in polyols, which makes it possible to prepare a catalyst concentrate in polyols used as isocyanate-active compounds in the preparation of polyurethane.
