Organosilicon compounds containing silazane and siloxane linkages
Abstract
Abstract ORGANOSILICON COMPOUNDS HAVING BOTH SILAZANE (SI-NSI) AND SILOXANE (SI-O-SI) LINKAGES ARE PREPARED BY REACTING (1) A HYDROXYL CONTAINING ORGANIC OR ORANOSILICON MATERIAL WITH (2) A CYCLIC SILAZANE OR CYCLIC SILOXAZANE HAVING FROM 6 TO 12 MEMBERS IN THE CYCLIC STRUCTURE AND 1, 2 OR 3 GROUPS OF THE GENERAL FORMULA (R2-SI)2-N-SI(-R''2)-O-SI(-R''2))N-N(-R")2 WHERE THE FREE VALENCE BOND ON EACH OF THE SI* ATOMS IS ATTACHED TO ANOTHER MEMBER OF THE CYCLIC SILAZANE OR SILOXAZANE STRUCTURE, R IS ANY MONOVALENT HYDROCARBON RADICAL OF LESS THAN 7 CARBON ATOMS, R'' IS A MONOVALENT HYDROCARBON OR HALOGENOHYDROCARBON RADICAL OF 1 TO 18 CARBON ATOMS, R" IS H OR AN ALKYL RADICAL OF 1 TO 5 CARBON ATOMS AND N IS 0 TO 1.
