FIELD: chemistry.
SUBSTANCE: mixture consists of polyols expressed by compositions 
and 
. Besides there is disclosed method for producing mixed polyols including (i) mixing of the initiator representing polyol, polyamine, amino alcohol or their mixture, and monomer of at least one formula 
, 
and 
, herewith amount of composition (III) is at least 0.05 wt % of mixed polyols and (ii) heating of the mixture to reaction temperature, during reaction time, in vacuum and with the catalyst added, and method for making mixed polyols, including (i) heating with the catalyst added, of monomer described by least one formula (I), (II) and (III), and amount of composition (III) is at least 0.05 wt % of mixed polyols until some monomers react, and then (ii) adding of the initiator during time and at temperature sufficient to produce mixed polyols in vacuum environment, as well as polyurethane containing interaction product of polyisocyanate and specified mixed polyols.
EFFECT: mixed polyols are characterised with high molecular weight without gelling, application of such mixed polyols in foamed polyurethanes production improves pore size of foam plastics, pore structure, touch perception or tactile quality and its wear resistance.
