Patent application number | Description | Published |
20080286628 | Particles Comprising Zwitterionic Structural Elements - Solid particles bearing zwitterionic functional groups exhibit properties unlike other functionalized particles, and are particularly useful as proton-conductive fillers in membranes for fuel cells, where they increase physical properties as well as charge conducting properties. The particles are prepared by reacting functionalized particles with zwitterionic group-containing silanes or siloxanes. | 11-20-2008 |
20090105358 | SILICONE-CONTAINING FOAMS - Foamable, isocyanate-functional organopolysiloxanes with more uniform molecular weights are produced by reaction of an aminoalkyl or hydroxyalkyl functional organopolysiloxane with a stoichiometric excess of a di- or polysiocyanate in the presence of a compatibilizer which provides a homogenous reaction mixture. | 04-23-2009 |
20090149595 | SILICONE POLYMERS CROSSLINKABLE VIA METHYLOL GROUPS - Storage stable compounds having at least two organopolysiloxane groups and at least one methylol group are useful as coatings on textile, paper, and other substrates, and are post-crosslinkable. | 06-11-2009 |
20090186982 | ORGANOSILICONE COPOLYMERS - Organosilicon polymers prepared by copolymerizing an unsaturated methylol compound, an unsaturated monomer, and an organopolysiloxane bearing at least one unsaturated group exhibit good binding and crosslinking properties when applied to fibers, and the ability to tailor substrate hydrophobicity. | 07-23-2009 |
20100069551 | ULTRAHYDROPHOBIC COATINGS - Ultrahydrophobic coatings are prepared by coating a substrate with a coating system containing an addition polymer containing moieties derived from a mono- or polyethylenically unsaturated organopolysiloxane, and hydrophillic particles. | 03-18-2010 |
20100081765 | FREE-RADICAL POLYMERIZATION PROCESS - The invention relates to a process for free-radically initiated heterophase polymerization, in which the polymerization of ethylenically monomers proceeds in a phase dispersed in the continuous phase, characterized in that one or more additives which are soluble in the continuous phase and insoluble in the disperse phase and stop the polymerization of the ethylenically unsaturated monomers in the continuous phase is/are added before or during the polymerization. | 04-01-2010 |
20100222504 | SILANE-SUBSTITUTED RAFT-REAGENTS AND SILANE-CROSS-LINKABLE POLYMERS - Addition polymers prepared in the presence of condensation-crosslinkable silyl-functional RAFT reagents are preparable in solid or liquid form with low polydispersion. | 09-02-2010 |
20100267854 | POLYURETHANE FOAM CONTAINING SILICONE - Silicone-containing polyurethane foams of low density may be prepared from hyperbranched siloxanes. | 10-21-2010 |
