Abstract: The invention relates to amino organic substances of the general formula (CoBnAm) -N-R'-N-(AmBnCo) (F1), wherein m, n and o are natural integers, which satisfy the condition m + n + o = 2, and the substituents have the following structures (a), wherein the substituents R', R'' and R''' have the following chemical composition: R' represents alkyl, cycloalkyl groups, R'' represents alkyl, cycloalkyl, alkylene, alkyldiene, alkyline, phenyl, mono- and polyfluoralkyl groups, R''' represents (CH2)z-CH3 with z = 2-16, wherein X is a polyalkylether chain. The invention further relates to a method for producing the inventive substances, to their use as additives in the production of PUR and PIR, especially as foam stabilizers in the production of PUR and PIR foams, and to the corresponding foam stabilizers as such.

Abstract: Polyester polyol is prepared by polycondensation of an alcohol/ester mixture with a carboxylic acid mixture and polyalkylene terephthalate. Polyester polyols (I) based on alcohols and carboxylic acids and/or carboxylic acid derivatives as well as polyalkylene terephthalate are prepared by polycondensation of a raw material mixture containing (A) a mixture of one or more alcohols having at least 2 hydroxyl groups and 10-30 wt.% of a linear and/or cyclic ester compound, (B) a mixture of 10-33 wt.% succinic acid, 39-50 wt.% glutaric acid and 16-45 wt.% adipic acid and (C) polyalkylene terephthalate whereby the wt. ratio of (A):(B):(C) is 35-60:10-25:20-55.
