PCT No. PCT/NL93/00070 Sec. 371 Date Jan. 9, 1995 Sec. 102(e) Date Jan. 9, 1995 PCT Filed Mar. 25, 1993 PCT Pub. No. WO93/20050 PCT Pub. Date Oct. 14, 1993.The invention relates to novel bis-iminoazacyclo pentane polyols according to the formula given below, wherein R1=H, alkyl or R4, whereby R4 is OH, hydroxyalkyl, hydroxyaryl or hydroxyaralkyl and R2 and R3 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 vinylpolymer 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.
