Abstract
Abstract A PROCESS HAS BEEN PROVIDED FOR POLYMERIZING A PARTICULAR TERMONOMER SYSTEM ONTO SURFACES OF SILICEOUS SUBSTNCES. BY VARYING THE COMPONENT PARTS OF THE TERMONOMER SYSTEM, MODIFIED SILICEOUS SUBSTANCES, SUCH AS CLAYS AND SILICAS, ARE OBTAINED WHICH MAY POSSESS DIVERSE PROPERTIES, ONE FROM THE OTHER. MOREOVER, MODIFIED SILICEOUS SUBSTANCES MAY BE 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 POLY(ESTER) AND OLEGINOUS COMPOSITION FORMULATIONS. THE PARTICULAR TERMONOMER SYSTEM CONSISTS OF A MAJOR MONOMER, M1; A MONOMER WHICH REGULATES THE POLARITY OF THE SYSTEM, M2; AND A MONOMER, M3, WHICH CROSS-LINKS AND THUS PREVENTS DISPLACEMENT OF THE POLYMERIZATE OF M1, M2 AND M3 FROM THE SURFACE OF THE SILICEOUS SUBSTANCE WHEN THE SILICEOUS SUBSTANCE IS INCORPORATED SUCH AS IN POLY(ESTER). AN EXAMPLE OF SUITABLE TERMONOMER SYSTEMS IS STYRENE, DIMETHYLAMINO ETHYL METHACRYLATE AND DIVINYLBENZENE IN A WEIGHT RATIO OF 98:2:0.1, RESPECTIVELY.
