    Abstract: External donor systems, catalyst systems and olefin polymerization processes are described herein. The external donor systems generally include a first external donor represented by the general formula SiR2m(OR3)4-m, wherein each R2 is independently selected from alkyls, cycloalkyls, aryls and vinyls, each R3 is independently selected from alkyls and m is from 0 to 4. The external donor systems further include a second external donor represented by the general formula SiR4m(OR5)4-m, wherein each R4 is independently selected from alkyls, cycloalkyls, aryls and vinyls, each R5 is independently selected from alkyls, m is from 0 to 4 and at least one R4 is a C3 or greater alkyl.

  • Publication number: 20080132721
    Abstract: Alkoxysilanes are prepared by a process which uses microwave or RF energy. Thus, silicon metal and a copper catalyst are exposed to microwave radiation in the presence of an appropriate hydroxy compound, such as, an alcohol, and a catalyst, to yield the corresponding trialkoxysilane. The desired alkoxysilanes are prepared with high selectivity and at lower temperatures and shorter times than traditional approaches allow.

  • Publication number: 20080103323
    Abstract: The present invention provides a process for using nanosized copper, nanosized copper oxides, nanosized copper chlorides, other nanosized copper salts, and mixtures thereof, as sources of catalytic copper in the Direct Synthesis of trialkoxysilanes of the formula HSi(OR)3 wherein R is an alkyl group containing from 1 to 6 carbon atoms inclusive. The nanosized copper, nanosized copper oxides, nanosized copper chlorides, other nanosized copper salts, and their mixtures of this invention have average particle sizes that are in the range from about 0.1 to about 60 nanometers, preferably from about 0.1 to about 30 nanometers, and most preferably from about 0.1 to about 15 nanometers. Nanosized sources of catalytic copper afford high dispersion of catalytic sites on silicon and contribute to high reaction rates, high selectivity and high silicon conversion. The nanosized copper catalyst precursors of the invention permit the use of substantially reduced levels of copper compared to conventional practice.

  • Patent number: 7109281
    Abstract: This invention relates to the reversible protection of hydroxy-silane functional groups by acid cleavable protecting groups. The development of reversible protecting groups greatly enhances the current utility of silanes while introducing further novel applications. For instance, reversibly protected silanes are of particular value in applications where room temperature cure and/or adhesion is of value, such as coatings, high resolution imaging, caulks, adhesives, sealants, gaskets, and silicones. Reversibly protected silanes can also be beneficially used in reticulating agents, and in sizing agents, tires, and release coatings. The incorporation of reversibly protected silanes into coating resins is of particular value. The reversibly protected silane can be incorporated into the coating resin by polymerizing a monomer containing the reversibly protected silane into the resin or by post-addition into the coating formulation.
