Patent number: 6713534Abstract: A fine-particle, free-flowing rubber powder containing silicatic fillers, one or more organosilanes having trialkoxysilyl groups, and a rubber prepared by solution polymerization is prepared by a process that starts from a two-phase system: 1) filler in water, and 2) rubber in organic solvent. A rubber/silicatic filler/silane composite is formed during transfer, under gentle conditions, of the various reactants into a single phase. The process features a high degree of freedom in selecting forms of filler and in selecting the organosilane and gives a finished rubber powder in which a silicatic filler and an organosilane have undergone complete chemical reaction.Type: GrantFiled: April 10, 2002Date of Patent: March 30, 2004Assignee: PKU Pulverkautschuk Union GmbHInventors: Udo Goerl, Matthias Schmitt, Reinhard Stober, Andreas Gouw
