Flame-retardant phosphorus-functional polyether carbonate polyol and method for production thereof

The present invention relates to a method for producing an organooxysilyl-crosslinked polymer by reacting a polyether carbonate polyol which contains carbon-carbon double bonds with a polysiloxane compound in the presence of a suitable catalyst. Suitable polysiloxane compounds have at least two Si&#x2014;H bonds. This invention also relates to organooxysilyl-crosslinked polymers which are formed by this process.

Method for producing a polymer which contains double bonds as an elastomer precursor

The invention relates to a method for producing an isocyanate, wherein a carbamate or thiolcarbomate is converted, in the presence of a catalyst, with separation of an alcohol or thioalcohol, at a temperature of at least 150&#xb0; C., to the corresponding isocyanate, wherein a compound of the general formula (X)(Y)(Z&#x2014;H) is used as a catalyst, in particular characterized in that the compound has both a proton donor function and a proton acceptor function. In the catalysts according to the invention, a separable proton is bound to a heteroatom, which is more electronegative than carbon. Said heteroatom is either identical to Z or a component thereof. In the catalysts according to the invention, there is additionally a proton acceptor function which is either identical to X or a component thereof. According to the invention, the proton donator and proton acceptor function are connected to each other by the bridge Y.

Method for producing isocyanates

The invention relates to the use of substituted dihydrooxindolylsulfonamides or salts thereof of the formula (I) where the radicals in the general formula (I) correspond to the definitions given in the description, for enhancing stress tolerance in plants to abiotic stress, and/or for increasing plant yield.
