Abstract
The present invention discloses a process for producing a polyurethane product with autocatalytic polyols. These auto-catalytic polyols are based on an initiator of the formula (I): H A-(CH ) —N(R)-(CH ) -AH where n and p are independently integers from 2 to 6, A at each occurrence is independently oxygen, nitrogen or hydrogen, with the proviso that only one of A can be hydrogen at one time, R is a C to C alkyl group, m is equal to 0 when A is hydrogen, is 1 when A B is oxygen and is 2 when A is nitrogen; or are polyols which contain an alkyl amine of within the polyol chain or a dialkylylamino group pendant to the polyol chain wherein the polyol chain is obtained by copolymerization of at least one monomer containing an alkyl aziridine or N,N-dialkyl glycidylamine with at least one alkylene oxide. These auto-catalytic polyols are reacted with a polyisocyanate in the presence of other additives and/or auxiliary agents known per se to produce polyurethane products.
