N-SUBSTITUTED HYDROXYALKYL/-ARYL/-ARALKYL-2,5-BISIMINOPYRROZIDINES, PROCESS FOR THEIR MANUFACTURE AND USE AS A POLYOL-COMPONENT IN POLYCONDENSATION REACTIONS

摘要

The invention relates to novel bis-iminoazacyclo pentane polyols according to formula (1), wherein R<1> = H, alkyl or R<4>, whereby R<4> is OH, hydroxyalkyl, hydroxyaryl or hydroxyaralkyl and R<2> and R<3> are independently of one another, OH, hydroxyalkyl, hydroxyaryl or hydroxyaralkyl which are obtainable by reaction of succinonitrile with a hydroxyalkylamine, to polyols obtained on the basis of such compounds, in which a polyether, a polyester or a venyl-polymer or combinations thereof are also incorporated, and to polymers in which said polyols are incorporated. Polyurethane foam in which 1-(hydroxyethyl)-2,5-bis-(2-hydroxyethylimino)-azacyclopentane is incorporated shows a higher mechanical strength and reduced inflammability, whilst the formulation has an increased reactivity.
