POLYURETHANE FOAM PRODUCTION PROCESS AND POLYURETHANE FOAM THUS OBTAINED Russian patent published in 2008 - IPC C08G65/26 C08G18/48 C08G18/00 

FIELD: polymer production.

SUBSTANCE: process comprises interaction of (a) polyol component, containing at least one polyoxyalkylenated polyether-polyol obtained in the form of aluminum phosphonate-based catalyst and having average equivalent weight from about 100 to about 10000, with (b) organic isocyanate in presence of (c) if necessary, one or several lengtheners, (d) if necessary, catalyst, foaming agent and (e) if necessary, crosslinking agents, surfactants, fire retardants, pigments, antioxidants, and stabilizers. Polyurethane foam obtained as described above is also described as well as catalyst based on aluminum phosphonate and having general formula RPO-(AAlR'R")2, wherein P denotes pentavalent phosphorus, O oxygen, Al aluminum, R hydrogen, alkyl or aryl group, and R' and R", independently from each other, halogen, alkyl group, aryl group, aryloxyl group, or derivatives of thus specified aluminum phosphonate, in amount from about 0.001 to about 5.0% based on the total weight.

EFFECT: improved quality, in particular homogeneity of polyurethane foam.
