Abstract: A process for the production of flexible polyurethane foam comprises reacting: (a) optionally modified polyisocyanates with: (b) compounds with reactive hydrogens, and (c) optionally chain extenders and/or crosslinkers, in presence of: (d) blowing agents, (e) catalysts, (f) fire retardants, and optionally: (g) other additives etc. At least 10 wt% of the compounds used in this process comprises polyether-polyols obtained by base-catalysed reaction of lower alkylene oxides with hydroxy-functional starters and subjected, during or after alkylene oxides-addition and with a water content of not more than 0.1 wt.%, to distillation at temperatures above 49 degrees C.

Abstract: Reactive amide-containing polymers (I). Reactive polymers of formula (I) are new L-(-Z -OCNH-A(-NHCO-Z -B-XY)n)m (I) L = polymer, free of urethane groups and with number average molecular weight at least 300, or any linear or branched sequences of two or more such polymers; A = optionally unsaturated 2-12C alkylene, cycloalkylene, 3-18C arylene or 7-18C arylenealkylene (all optionally substituted) or a heterocyclic group, or any branched or linear combination of them; Z and Z = NR, sulfur or oxygen; R = hydrogen, methyl, optionally unsaturated 2-12C alkyl, cycloalkyl, or 3-18C aryl (all optionally substituted), or any branched or linear combination of them; B = bond, methylene, or alkylene, cycloalkylene or arylene, or their combinations, as above; n = 1-20; m = 1-50; XY = a group unreactive with isocyanato groups from which the protecting group Y can be removed, under acidic, neutral or basic conditions, to produce a group containing at least two groups reactive with isocyanato . Independent claims are also included for the following: (a) method for preparing (I); (b) polymers (II) with at least two urethane or urea groups and, based on these groups, twice the number of functional groups reactive with isocyanato, produced by hydrolysis of (I); (c) polyaddition and polycondensation products prepared from (II); and (d) method for doubling the number of groups reactive with isocyanato in a urethane-free polymer.
