The present invention relates to polysiloxane polyether copolymers which comprise at least one (polyether) moiety which comprises at least one unit &#x2014;O&#x2014;C(O)&#x2014;O&#x2014;, to a process for the production of the polysiloxane polyether copolymers, and also to the use of the polysiloxane polyether copolymers as stabilizers in the production of polyurethane foams, and also to polyurethane foams and items therefrom which are obtainable through the process.

Polysiloxane polyether copolymers having (polyether)moieties comprising carbonate groups and their use as stabilizers for the production of polyurethane foams

The present invention relates to the use of nitrogenous compounds of formula (I) or of corresponding quaternized, or protonated compounds, for producing polyurethanes, to compositions containing these compounds and also to polyurethane systems obtained using the compounds.

Amines suitable for use in the manufacture of polyurethanes

The invention relates to a catalyst system that is suitable for catalyzing the production of polyurethane foams. The catalyst system is characterized in that said system contains a metal salt of an alcohol that is modified with an acid end group.

Production and use of metal salts of alkyl oxide and/or aryl alkyl oxide oligomers and polymers with acid end groups in the production of polyurethane systems

The present invention relates to a process for preparing branched polyethers and/or polyether-like structures, to these branched polyethers themselves, and to their use.

Process for preparing branched polyethercarbonates and use thereof

The invention relates to a method for producing alkaline amides or imides of ethylenically unsaturated Cto Ccarboxylic acids by reacting amines that contain at least one primary and/or secondary amino group and at least one tertiary amino group with ethylenically unsaturated Cto Ccarboxlic acids to form an ammonium salt and said ammonium salt is subsequently converted into the alkaline amide or imide by means of microwave radiation, with the proviso that the primary and/or secondary amino group is devoid of alkoxy groups.

Method for producing alkaline (meth)acrylamides

A catalyst system which is suitable for catalyzing the production of polyurethane systems is provided. The catalyst system contains a metal salt of a carboxylic acid to whose carbonyl carbon a hydrogen atom or a hydrocarbon radical is bound, with the proviso that the carboxylic acid does not have exclusively a single ethyl or n-propyl branch in the 2 position.

Use of metal salts of a carboxylic acid in the production of polyurethane systems

The invention relates to a method for producing fatty acid alkanol amides by reacting at least one amine that contains at least one primary or secondary amino group and at least one hydroxyl group with at least one fatty acid to form an ammonium salt, said ammonium salt being subsequently converted into the alkanol amide by means of microwave radiation.

Method for producing fatty acid alkanol amides

The invention relates to a method for producing bisbenzoxazoles that are interconnected by means of a system of conjugated double bonds, according to which o-aminophenols are reacted with dicarboxylic acids, the carboxyl groups of which are interconnected via a double bond or a system of conjugated double bonds, to form an ammonium salt, said ammonium salt being converted in the presence of dehydrogenating catalysts and solvents with a low dielectric loss into benzoxazol by means of microwave radiation.

Method for producing bisbenzoxazoles

The invention relates to a method for producing tertiary amides of alkylphenyl carboxylic acids by reacting at least one secondary amine with at least one alkylphenyl carboxylic acid to form an ammonium salt, said ammonium salt being subsequently converted into the tertiary amide by means of microwave radiation.

Method for producing tertiary amides of alkylphenyl carboxylic acids

The invention provides a process for preparing amides from polyetheramines and (meth)acrylic acid or the corresponding anhydrides, the energy source used being microwaves.
