  • POLYSILOXANE GRAFT POLYMER
    Publication number: 20070213474
    Abstract: Particulate additives which may be added to thermoset or thermoplastic polymers while maintaining transparency comprise core/shell polysiloxane graft polymers having a silicone core, optionally an inner addition polymer core within the silicone core, and an addition polymer shell. The silicone core is derived from at least one monomer having conjugated electron pairs.

  • Thermocurable, one-component, addition-crosslinking silicone compositions
    Patent number: 6251969
    Abstract: Organopolysiloxane particles containing hydrosilylation catalysts (H) and organopolysiloxane (O) and having a particle size of 0.01-10 &mgr;m have, at least in the outermost shell, no glass-transition temperature, softening point or melting point in the range 20° C.-260° C. These organopolysiloxane particles enable the preparation of one-component, addition-crosslinking, thermocurable silicone compositions having a long shelf life.
