Abstract: A PROCESS HAS BEEN PROVIDED FOR POLYMERIZING DIACETONE ACRYLAMIDE MONOMER AND A COMONOMER SYSTEM BASED ON DIACETONE ACRYHLAMIDE MONOMER ONTO A PARTICULATE CALCIUM CARBONATE; THIS PROCESS MAY BE CARRIED OUT IN AN AQUEOUS PHASE; THE MONOMERS OR COMONOMERS ARE POLYMERIZED VIA FREE RADICAL POLYMERIZATION ONTO THE SURFACE OF CALCIUM CARBONATE; WHEN CALCIUM CARBONATE IS MODIFIED WITH DIACETONE ACRYLAMIDE HOMOPOLYMER, IT POSSESSES IMPROVED PROPERTIES; BY EMPLOYING DIACETONE ACRYLAMIDE AS ONE OF THE MONOMER PRECURSORS IN A COMONOMER SYSTEM BUT BY VARYING THE AMOUNT OF COMONOMER, MODIFIED CALCIUM CARBONATE IS OBTAINED WHICH POSSESSES ESPECIALLY ADVANTAGEOUS PROPERTIES; 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, PAINT, PUTTY, CAULKING AND GROUTING COMPOSITION FORMULATIONS, TO NAME A FEW.
