    A silane functionalized styrene monomer and its polymerization (1995)
    Springer
    Journal of inorganic and organometallic polymers and materials 5 (1995), S. 43-59 
    Details
    ISSN: 1572-8870
    Keywords: Hyperbranched polymers ; hydrosilylation polymerization ; styrene siloxane copolymers ; poly(siloxysilanes) ; radical polymerization

    Topics: Chemistry and Pharmacology
    Notes: Abstract Synthetic methodology for a new monomer, (4-vinylphenyl)tris(dimethylsiloxy) silane (3), which can be polymerized to give either hyperbranched polymers or linear polymers has been developed. Hyperbranched polymers can be prepared from the monomer via hydrosilation. Monomer3 can undergo free radical polymerization, which yields a linear homopolymer. Copolymers with styrene have also been prepared. The resulting polymers, which contain pendant silicon hydride functionality, can be functionalized with a variety of reagents. The glass transition temperature was found to depend strongly on the amount of silicon incorporated into the polymers.

    Hydrosilylation catalysts derived from cyclodextrin organometallic platinum inclusion compounds and their use in command-cure applications (1996)
    Springer
    Journal of inorganic and organometallic polymers and materials 6 (1996), S. 123-144 
    Details
    ISSN: 1572-8870
    Keywords: Hydrosilylation catalysts ; cyclodextrin organometallic platinum inclusion compounds ; command-cure ; β-cyclodextrin
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract Beta-cyclodextrin (β-CD) complexes of CODPtX 2 (COD=1.5-cyclooctadiene.X=Cl, Br, and I) have been prepared and employed as hydrosilylation catalysts. When used in cross-linkable, silicone-containing systems, these catalysts provide a long shelf stability at ambient temperature but cure rapidly at elevated temperature. These systems thus have the property of “command-cure”. Extensive analytical investigations were undertaken to develop reproducible synthetic methodology for the preparation of inclusion compounds free of surface contamination of the guest platinum compound. Water plays a key role in the synthesis of such platinum inclusion compounds. Dried β-CD CODPtX 2 compounds can be washed with organic solvent to remove residual uncomplexed CODPtX 2, while organic solvent washing of wet inclusion compounds results in removal of the guest from the β-CD cavity. Examination of these catalysts in curable silicone systems is described.
