摘要:
The present invention pertains to a process for preparing a modified inorganic oxygen-containing particulate material comprising the steps of: a) preparing a mixture of an aqueous suspension of inorganic oxygen-containing particulate material and an alkoxylated alcohol according to the formula (I) wherein R 1 is a C 1 -C 8 alkyl, C 4 -C 8 cycloalkyl or phenyl, R 2 is hydrogen or methyl, and n is an integer from 1 to 5; b) optionally adding a first resin and/or a first resin precursor; c) adding one or more coupling agents to the mixture; d) optionally adding a second resin and/or a second resin precursor to the resulting mixture; and wherein optionally water is removed at least partially from the mixture before or during step b), c) or d), or after step d); and optionally converting the first resin precursor into the first resin before, during or after step c) and/or the second resin precursor into the second resin after step d).
摘要:
The present invention pertains to an aqueous slurry comprising inorganic oxygen-containing particulates having an average particle size below 165 nm, wherein the slurry comprises inorganic oxygen-containing particulates which have been modified with a silane coupling agent having a functional group selected from the group consisting of R1O-CO-, (R2)2N-, R3O-, and R4S-, wherein R1, R2, R3, and R4 are independently chosen from H and a hydrocarbon comprising from 1 to 24 carbon atoms and optionally comprising a heteroatom, with the proviso that the inorganic oxygen-containing particulate is not silicon dioxide, as well as to the process to make these slurries and the use of such slurries.
