Abstract: The invention relates to highly reactive polyoxyalkylenepolyols prepared by oxalkylation of an initiator molecule containing at least 2 reactive hydrogen atoms and at least one tertiary amino group bonded via a spacer bridge, which preferably comprises an alkylene radical having at least 3 carbon atoms, by means of at least one alkylene oxide, preferably ethylene oxide and/or 1,2-propylene oxide, to a process for the preparation of these polyoxyalkylenepolyols, and to their use for the preparation of compact or cellular, preferably flexible, polyisocyanate polyaddition products.

Abstract: The invention relates to a composite element comprising A) at least one top layer of polyvinyl chloride or a polyvinyl chloride-containing polymer mixture, and B) a preferably semi-rigid or rigid polyurethane foam, where the top layer (A) or the polyurethane foam (B) or both constituents (A) and (B) contain units of an alpha , beta -olefinically unsaturated polyester having a molecular weight factor of from 150 to 3000 per double bond, to a process for the production of composite elements of this type, and to liquid, urethane group-containing polyisocyanate mixtures based on diphenylmethane diisocyanates and higher homologues thereof and alpha , beta -olefinically unsaturated polyesters for the preparation of polyurethane foams (B).

IPC: C08G18/50
Abstract: In prodn. of polyurethane foams by reaction of (a) an at least difunctional polyoxyalkylene polyol and (b) opt. a low-mol. chain-extender, with (c) a (modified) organic polyisocyanate, in presence of (d) opt. catalysts, (e) blowing agents and (f) opt. aids and/or additives. The polyol contains a combined bridging gp. of formula (I), where R and R1 are 1-12C (un)branched alkyl. USE/ADVANTAGE - The stability against hydrolysis of polyurethane (PU) compsns. for PU foams, esp. soft foams, is improved, without affecting the reactivity of the compsn. The cycle time is short and the foams can quickly be demoulded. The foams are used in vehicles, furniture and the sport and leisure industries, e.g. as cushions, arm rests, head supports, sunblinds, and safety coverings, esp. in vehicles and aircraft, as inner protection in mountaineering and ski boots and as shoe soles.
