Process for producing flexible polyurethane foams in particular molded flexible polyurethane foams, by reacting

Method for producing polyrethane soft foam materials

Polyester-polyether block copolymers can be prepared by catalytic addition of alkylene oxides onto H-functional initiator substances, using polyester alcohols as H-functional initiator substances and multimetal cyanide compounds as catalysts.

Polyester-polyether block copolymers

In a process for preparing polyether alcohols by catalytic addition of at least two alkylene oxides onto H-functional initiator substances, at least one multimetal cyanide compound is used as catalyst and the addition of the alkylene oxides onto the initiator substance includes incorporation of at least one oxyalkylene block during whose formation at least two alkylene oxides are metered in together and the ratio of the alkylene oxides to one another in the mixture is changed during the joint introduction.

Method for production of polyether alcohols

Sound-damping and energy-absorbing flexible PUR foams are produced by reacting organic and/or modified organic polyisocyanates (a) with a polyetherol mixture (b) and, if desired, further compounds (c) bearing hydrogen atoms which are reactive toward isocyanates, in the presence of water and/or other blowing agents (d), catalysts (e) and, if desired, further auxiliaries and additives (f).

Production of polyurethane foams

A process for preparing a homogeneous polyol component which is stable to separation and consists of at least one compound of relatively high molecular weight having at least two reactive hydrogen atoms and low-molecular-weight chain extenders and/or crosslinkers and, if desired, of blowing agents, catalysts and other auxiliaries and/or additives comprises the addition to this component of at least one amine and at least one organic and/or modified organic isocyanate; the invention also provides the corresponding polyol component which is stable to separation. The use of this polyol component for preparing PUR, in particular compact or foamed PUR, is also described.
