ELASTOMER COMPOSITIONS WITH SILANE FUNCTIONALIZED SILICA AS REINFORCING FILLERS

摘要

Certain embodiments described herein are directed to silane functionalized fillers that may be, for example, covalently coupled to a polymer. In some examples, devices that include the filler reinforced polymer compositions are also described.

主权项

1. A method comprising:
reacting a filler with at least one silane coupling agent having the formula Qm-Si—Zn, where Z comprises one or more groups that can provide covalent attachment to the filler, Q is —R″-G or —CR′2—CR′—R″-G, where R′ is a hydrogen or a fluorine, R″ is optional and is a linear or branched C1-C18 alkyl group, optionally containing one or more ether oxygen atoms and optionally fluorinated, G is a halogen, a nitrile group, or a vinyl group, and the sum of m+n is equal to four to covalently couple the silane to the filler; and reacting the covalently coupled silane-filler with a polymer to covalently couple the polymer to the covalently coupled silane-filler.
