TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The first and/or second solvents are alkoxylated alcohols of formula R1-(O-CH2-CH(R2))n-OH (I).    TECHNOLOGY FOCUS - POLYMERS - Preferred Process: The process involves: (a1) preparing a mixture of an aqueous suspension of inorganic oxygen-containing particulate material and an alkoxylated alcohol of formula R1-(O-CH2-CH(R2))n-OH (I); (b1) optionally contacting the mixture with at least one monomer and optionally polymerizing the monomer(s) to form the rubber precursor, and/or with at least one rubber precursor; (c1) contacting at least one coupling agent with the mixture and modifying the particulate material at least partially; (d1) optionally contacting at least one monomer with the resulting mixture and polymerizing the monomer(s) to form a rubber precursor, or contacting at least one rubber precursor with the resulting mixture; (e1) optionally curing the rubber precursors; and optionally removing water and/or the alkoxylated alcohol.R1=1-4C alkyl;R2=H or methyl;n=1-5.Preferred Components: The monomer is a coupling agent. The coupling agent comprises a functional group reactive with the particulate material and an organic group reactive with the rubber or with a rubber precursor. EXAMPLE - Into a 3-litre three-necked round-bottomed flask equipped with a mechanical stirrer, a thermometer, and a distillation unit Nyacol 2034DI (RTM: colloidal silica) (647 g), containing silica (222.56 g) and ethyl proxitol (970.5 g) were weighed. The temperature was raised to 38 degrees C and the pressure were reduced to 60 mbar in order to distill a water/solvent mixture. During a period of 3 hours the pressure was slowly reduced to 40 mbar to obtained an organosol with a water content of 2.4 wt.% and nano-silica solid content of 30.7 wt.%. Into a 250-ml four-necked round-bottomed flask equipped with a mechanical stirrer, dropping funnel, reflux condenser, and a thermometer the organosol (131.51 g) containing modified nano-silica (40.4 g), were weighed. The temperature was raised to 110 degrees C and next a mixture of vinyl thmethoxy silane (19.08 g), water (8.35 g), Nyacol 2034DI (RTM: colloidal silica) (0.1 g), and ethyl proxitol (38.16 g) was dosed over a period of 100 minutes. The temperature was next raised to 130 degrees C to distill off volatiles resulting from the silane and a part of the solvent to obtained modified nano-silica (A1) (36.35 wt.%). A two-component Pt cured silicone resin (test) consisting of the modified nano-silica (A1) (component A) (2 wt.%) which does not contain the Pt catalyst, and a component B containing the Pt catalyst. The component A was mixed with component B, followed by de-aeration in a vacuum oven at room temperature. Two foils made of ethylene-tetrafluoroethylene copolymer (ETFE; surface modified ETFE) were adhered to each other using the modified silicone resin. The modified silicone resin was then cured for 20 minutes at 120 degrees C using 2.5 bar pressure. A comparative an unmodified silicone was prepared similarly without adding the modified nano-silica (A1) to the component A. The adhesion and the strength of the silicone rubbers were determined. The test/comparative showed peel strength of 18/13 N/cm. The results showed that addition of the modified nano-silica (A1) improves the strength.
