Poly(diacetone acrylamide) modified kaolin
Abstract
Abstract A PROCESS HAS BEEN PROVIDED FOR POLYMERIZING DIACETONE ACRYLAMIDE MONOMER AND A COMONOMER SYSTEM BASED ON DIACETONE ACRYLAMIDE MONOMER ONTO A HIGH SURFACE AREA SILICEOUS SUBSTANCE, E,G., KAOLIN CLAY, SILICA, ETC. THIS PROCESS MAY BE CARRIED OUT IN AN AQUEOUS PHASE. THE MONOMERS OR COMONOMERS ARE POLYMERIZED VIA FREE RADICAL POLYMERIZATION ONTO THE SURFACE OF THE SILICEOUS SUBSTANCE. DIACETONE ACRYLAMIDE HOMOPOLYMER MODIFIED SILICEOUS SUBSTANCES POSSESS IMPROVED PROPERTIES. BY EMPLOYING DIACETONE ACRYLAMIDE BUT BY VARYING THE COMPONENT PART OF THE COMONOMER SYSTEM, MODIFIED SILICEOUS SUBSTANCES, SUCH AS CLAYS, ARE OBTAINED WHICH POSSESS ESPECIALLY ADVANTAGEOUS PROPERTIES. MOREOVER, MODIFIED SILICEOUS SUBSTANCES ARE OBTAINED WITH PROPERTIES WHICH MEET SPECIFIED REQUIREMENTS, PRODUCTS PREPARED BY THIS PROCESS ARE WITHIN THE SCOPE OF THE INVENTION AS ARE THE USES OF THESE SURFACE MODIFIED PRODUCTS FOR PURPOSES AS ADJUVANTS IN POLYMERS, E.G., POLY(ESTER), POLY(VINYL CHLORIDE) AND IN OLEAGINOUS, ALKYD, ADHESIVE, PUTTY, AND GROUTING COMPOSITION FORMULATIONS, TO NAME A FEW.
