Addition products from olefinically unsaturated polyester-polyols and alkylene polyamines, process for their preparation analogous to the Michael-reaction, their use as an additive for synthetic resins on isocyanate base and for the preparation of polyisocyanurate foams containing polyurethane groups

摘要

1. An adduct obtained by a functionality of 2 to 6, a hydroxyl number of 20 procedure analogous to the Michael reaction, by reacting a) an olefinically unsaturated polyester polyol having to 800, an acid number of 0 to 15 and a molecular weight of 150 to 3000 per double blond, with b) 0.1 to 1 mole, per mole of olefinically unsaturated double bond of component (a), of an alkylene polyamine of the formula H2 N-R-NH-R'-X, where X is an NH2 or OH group, and R and R' are identical or different, linear or branched alkylene radicals of 2 to 12 carbon atoms.
