  • ALKOXYSILYL FUNCTIONAL OLIGOMERS AND PARTICLES SURFACE-MODIFIED THEREWITH
    Publication number: 20100004354
    Abstract: Oligomers are prepared by polymerizing unsaturated silanes, optionally along with a copolymerizable ethylenically unsaturated monomer. The oligomers are particularly useful for preparing core-shell particles.

  • Continuous production of aminofunctional siloxanes
    Publication number: 20070197757
    Abstract: Aminoalkyl-functional siloxanes are prepared efficiently by a continuous process in which a cyclic silazane and a hydroxyl-functional siloxane are fed continuously to a reaction zone, reacted in the reaction zone, and the aminoalkyl product and any unreacted starting materials are removed from the reaction zone. The process is effective even with hydroxyl-functional siloxanes having a very low weight percentage of hydroxyl groups.

  • Method for the production of organopolysiloxane copolymers and use thereof
    Publication number: 20060194937
    Abstract: A method for the solvent-free, continuous production of organopolysiloxane/polyurea/polyurethane block copolymers involves reacting amino-functional siloxanes with polyisocyanates and organic polyhydroxy compounds. The organopolysiloxane/polyurea/polyurethane block copolymers produced by means of the inventive method are useful for numerous purposes, for example as elastomers, caulks, sealants, and films.

  • Organopolysiloxane/polyurea/polyurethane block copolymers
    Patent number: 7026424
    Abstract: Organopolysiloxane/polyurea/polyurethane block copolymer elastomers exhibiting improved physical properties are prepared by reacting diisocyanates with aminoalkyl-functional organopolysiloxanes containing substantially no cyclic siloxanes, prepared by reacting a cyclic silazane with a bis(hydroxy)-organopolysiloxane. Traditional hydroxyl and amino-functional chain extenders may be reacted as well, to produce a wide range of block copolymer elastomers.
