  • Publication number: 20120226010
    Abstract: The present invention relates to a process for the production of an intermediate siloxane monomer and use of said monomer to produce high molecular weight linear polysilalkylenesiloxanes. The siloxane monomer is prepared by ring opening polymerization of a cyclic monomer of the structure in the presence of an acidic or basic ring opening polymerisation catalyst; to form a mixture of siloxane monomers and linear oligomers. The linear oligomers are then extracted and discarded before a further step of ring opening polymerization using the aforementioned intermediate siloxane monomer mixture as the starting material. The second polymerisation step is undertaken at a temperature within the melting point range of said siloxane monomer mixture. The intermediate, final product and methods of their manufacture are described.

  • Patent number: 8211547
    Abstract: An ultraviolet-curable silicone composition for a release paper including (A) 100 parts by mass of a specific organopolysiloxane having a polymerization degree of 8 to 20 and containing one epoxy group, and (C) an effective quantity of an onium salt photoinitiator. In a preferred embodiment, the composition further includes (B) 10 to 1,000 parts by mass of at least one specific organopolysiloxane containing a plurality of epoxy groups. In another preferred embodiment, the composition has a viscosity of not more than 100 mPa·s. The composition has a peel strength that exhibits a positive dependency on the peel speed when peeled from a hot-melt pressure-sensitive adhesive, and can therefore be used to produce a release paper capable of reducing peeling noise. Further, because the composition has a low viscosity, it exhibits excellent wetting of substrates having significant unevenness, even in a solventless form.
