  • Production of isocyanate functional organosilanes
    Patent number: 10155779
    Abstract: Isocyanate-functional silanes are prepared in high yield by pyrolysis of an O-carbamate prepared by reaction of a dialkylcarbonate with an aminoalkyl-functional silane in the presence of a basic catalyst, where the catalyst is neutralized by an acid which has a pKa of all protolysis stages of not more than 4. The neutralized or partially neutralized catalyst need not be removed prior to pyrolysis. The isocyanato-functional silanes exhibit higher storage stability as compared to those prepared from O-carbamates where catalyst neutralization is effected by weak acids.

  • Cross-linkable masses based on organyl-oxysilane-terminated polymers
    Patent number: 9920229
    Abstract: Moisture curable compositions having a low modulus and a high resilience are prepared by curing a composition containing a first polymer which predominately contains two moisture-curable silyl groups, and a second polymer which is terminated by an alkoxy group and contains but a single moisture-curable silyl group, or a hydroxyl group.

  • Method for producing carbamatoorganosilanes
    Patent number: 9914744
    Abstract: Carbamatoorganosilanes are produced in exceptionally high yield with a high degree of purity, by reacting an aminoorganosilane with a dialkylcarbonate in the presence of a basic catalyst, wherein a first reaction period proceeds at a temperature in the range of 35-65° C., followed by a later reaction period at a temperature at least 10° C. higher. A low level of catalyst allows its removal by simple exit filtration, without a separate filtration step.
