Abstract
PURPOSE: A polyalkylene oxide is used as a surface-modifying agent to treat the surface of a powder such as calcium oxide powder or clay, thus producing a reinforcing filler with greatly increased affinity and dispersibility to rubber and plastics.
CONSTITUTION: A powder of calcium carbonate or clay mainly composed of silica- alumina of less than 20 micron particle sizes is treated on the surfaces, with at least one selected from polyalkylene oxide, polyalkylene oxide alkyl ether, alkylphenyl ether, alkylester, alkyl thioether, alkylamine or alkylamide, containing polyalkylene oxide chain in the moleucle, and their mixtures. These polyalkylene oxides are mixed to prepare a surface modifier with wide molecular weight zone containing several molecular weight distribution and, preferably a copolymer of 1,000W100,000 average molecular weight, containing both blocks of polyethylene glycol and polypropylene glycol is included.
