Method of preparing isocyanurate containing organosilicon materials
Abstract
Abstract A METHOD IS PROVIDED FOR MAKING VARIOUS NITROGENCONTAINING ORGANOSILICON COMPOUNDS, SUCH AS SILYLORGANOISOCYANATES, THE CORRESPONDING CARBAMATE AND ISOCYANURATES. THE METHOD INVOLVES CONTACTING SILYLORGANOHALIDE AND A METAL CYANNATE IN THE PRESENCE OF A SUITABLE APROTIC SOLVENT. NITROGEN-CONTAINING ORGANOSILICON COMPOUNDS ARE PROVIDED HAVING SILICON AND NITOGEN ATOMS SEPARATED BY A DIVALENT HYDROCARBON RADICAL. IN INSTANCES WHERE A URETHANE IS DESIRED, AN APPROPRIATE ALIPHATIC MONOHYDRIC ALCOHOL CAN BE UTILIZED IN COMBINATION WITH THE SILYLORGANOHALIDE AND METAL CYANATE. THE SUBJECT NITROGEN-CONTAINING ORGANOSILICON COMPOUNDS CAN BE UTILIZED FOR MAKING SILICON-ORGANIC COPOLYMERS AND AS TREATING AGENTS FOR IMPARTING WATER REPELLENCY TO VARIOUS SUBSTRATES.
