AMINE-INITIATED POLYOLS AND RIGID POLYURETHANE FOAM MADE THEREFROM Russian patent published in 2012 - IPC C08G18/50 C08G65/26 C08J9/14 

FIELD: chemistry.

SUBSTANCE: amine-initiated polyol, having average functionality higher than 3.0 and less than 4.0, is a product of interaction of at least one C₂-C₄alkylene oxide with an aminocyclohexane alkylamine initiating compound, wherein said polyol has a hydroxyl equivalent mass from 75 to 560. The initiating compound is represented by any of the structures or , where each of the R groups independently denotes a hydrogen atom or C₁-C₄alkyl, R¹ denotes C₁-C₄alkyl, and m denotes a number from 1 to 8.

EFFECT: invention enables to obtain foam plastic with a good combination of low k-factor and short demoulding time.
