Abstract:
ROOM TEMPERATURE VULCANIZING SILICONE ELASTOMERS ARE PREPARED BY THE ADDITION OF A NOVEL CROSS-LINKING AGENT SUCH AS ACETOXYPROPENYLENYLTRIACETOXYSILANE TO A SILANOL CHAIN-STOPPED POLYDIORGANOSILOXANE FLUID. THESE COMPOSITIONS ARE STABLE, FREE FLOWING FLUIDS IN THE ABSENCE OF MOISTURE BUT CURE TO A RUBBERY, SOLID ELASTIC STATE UPON EXPOSURE TO MOISTURE. THESE COMPOSITONS ARE PARTICULARLY USEFUL AS ADHESIVES IN DIFFCULT BONDING SITUATIONS SUCH AS ATTACHING GLASS WINDOW PANES TO ALUMINUM WINDOW FRAMES.
Abstract:
New organosilicon chelates are formed from diketones and derivatives of diketones, where the silicon atom has functional substituents other than the diketone compound residue. The materials are useful as curing agents for room temperature vulcanizing materials.
Abstract:
Bis(aminoorganosilyl)hydrocarbons are employed in combination with organic diacids or organic dianhydrides to provide for the production of bis(organosilyl)hydrocarbon modified polyamides including polyamide acids. The bis(organosilyl)hydrocarbon modified polyamides also can contain chemically combined polydiorganosiloxane. The bis(organosilyl)hydrocarbon modified polyamides can be employed to make molding compounds, and polyamide and polyimide insulating films.
Abstract:
NEW ORGANOSILICON CHELATES ARE FORMED FROM DIKETONES AND DERIVATIVES OF DIKETONES, WHERE THE SILICON ATOM HAS FUNCTIONAL SUBSTITUENTS OTHER THAN THE DIKETONE COMPOUND RESIDUE. THE MATERIALS ARE USEFUL AS CURING AGENTS FOR ROOM TEMPERATURE VALCANIZING MATERIALS.
Abstract:
A ketonic hydrocarbon is converted to an enamine by heating a mixture of the ketonic hydrocarbon with an organosilane having at least one dialkylamino group directly attached to the silicon. In the reaction, the organosilicon is converted to a organopolysiloxane.
IS MADE BY HYDROGENATING THE CORRESPONDING NITRILE. IN THE ABOVE FORMULAS, A IS SIC BOND OR A HYDROGEN RADICAL, A IS A MONOVALENT ORGANIC RADICAL, R'' IS A MONOVALENT ORGANIC RADICAL OR HYDROGEN, X IS A HYDROLYZABLE GROUP, A HAS A VALUE OF 0 TO 3, AND B HAS A VALUE OF ONE TO 4. COMPOUNDS (1) AND (2) ARE USEFUL IN DETERGENT RESISTANT POLISH COMPOSITIONS.
Abstract:
Siloxanediolate/p-dioxane complexes and processes for preparing the complexes. Sodium or an amalgam thereof is reacted with arylsilicondiols in the presence of p-dioxane to form the complexes. Complexes are useful in preparing the corresponding aryl polysiloxanediols.
