A method for the production of polysilsesquioxane which contains - via train preparations and polymethyl - n - hexyl silsesquioxane having - via train preparations

摘要

process for the production of improved u00fcberzugszubereitung by combining alkyltrialkoxysilanen as n - hexyltrimethoxysilan and methyltrimethoxysilan manufacturers of silanes in the presence of a catalyst with at least one amino - replaced: functional group, at least one alkoxy - substituie attribute groupwhat is the alkoxy - substituted group at least two carbon atoms in the alkoxygruppe is a alkylgruppe and, where appropriate, in a volume smaller than a stoichiometric amount of water.the combined monomer, catalyst and water to produce an emulsion stirred by ultrasonic, the silanes to the degree of the existing water is allowed to feuchtigkeitshu00e4rtbare u00fcberzugszubereitung hydrolysed and produce.the present invention is a feuchtigkeitshu00e4rtbares u00fcberzugszubereitung the polymethyl - n - hexylsilsesquioxan, a partially water hydrolysed, manufacturers of silanes catalyst containing kondensationsprodukt of n - hexyltrimethoxysilan and methyltrimethoxysilan, whereby the catalyst zumi manufacturers of silanes find a aminoalkyl - substituted group and at least one alkoxy - substituted groupthe at least two carbon atoms in the alkoxygruppe has value. the manufacturers of silanes catalyst is also a co hu00e4rtungsmittel and condensed with the n - hexyltrimethoxysilan and methyltrimethoxysilan.
