Silyl acyl peroxides and acyl peroxy polysiloxanes

Abstract

Abstract THERE IS DESCRIBED HEREIN SILYL ACYL PEROXY COMPOUNDS CONTAINING AT LEAST ONE OF THE FOLLOWING STRUCTURES; (Z(3-X)-SI(-O(X/2))(-R'')-(NH)Y-COO)Z-(O-R")(2-Z) WHEREIN: R'' IS A DIVALENT HYDROCARBON SUCH AS ALKYLENE OR ARALKYLENE; R" IS ALKYL OR ARALKYL; Z IS ONE OR MORE OF A MONOVALENT HYDROLYZABLE RADICAL OR MONOVALENT ORGANIC RADICAL BONDED TO SI BY A CARBON TO SILICON BOND; X IS AN INTEGER FROM 0 TO 3 INCLUSIVE; WHEN X IS GREATER THAN 0 THE OXYGEN IS BONDED TO ANOTHER SILICON ATOM WHEREBY TO FORM A SILOXANE; Y IS 0 OR 1; Z IS 1 OR 2; AND PROVIDED THAT WHEN Y IS O, THE ACYL CARBONYL CARBON ATOM IS BONDED TO A CARBON ATOM OF R''; THE R'' HAVING AT LEAST TWO SEQUENTIAL CARBON ATOMS SEPARATING THE ACYL CARBONYL CARBON FROM THE SILICON; AND FURTHER PROVIDED THAT WHEN Y IS 1, Z IS 1 AND THE NITROGEN ATOM IS BONDED TO A CARBON ATOM OF R'', THE R'' HAVING AT LEAST 3 SEQUENTIAL CARBON ATOMS SEPARATING THE NITROGEN FROM THE SILICON. THESE COMPOUNDS ARE USEFUL AS COUPLING AGENTS AND BINDERS FOR POLYMER, RUBBER, SILICEOUS, METAL OXIDE AND METALLIC SUBSTRATES.
