20080255317 | Polyester-Polysiloxane Copolymers and Process for their Preparation - Polyester/polysiloxane copolymers are prepared by ring-opening synthesis of hydroxyalkyl- or aminoalkyl functional organopolysiloxanes from a cyclic silazane and an Si—OH functional polysiloxane, followed by reaction with a cyclic lactone such as a caprolactone. The process tolerates functional groups on the polysiloxane segments which are not possible in other synthetic methods. | 10-16-2008 |
20100007039 | METHOD FOR PRODUCING GRANULES FROM THERMOPLASTIC SILOXANE POLYMERS - Non-blocking polymer pellets are produced in spherical or nearly spherical form by introducing molten polymer directly from a polymerization reactor into a coolant and pelletizing just prior to, simultaneously with, or immediately following entry into the coolant such that residual heat allows the polymer pellets to change their shape to eliminate sharp corners, particularly cylindrical shapes, and assume a spherical-type morphology. | 01-14-2010 |
20100047589 | LAMINATES COMPRISING THERMOPLASTIC POLYSILOXANE-UREA COPOLYMERS - Photovoltaic modules are prepared by laminating an active device to a glass cover plate by means of a thermoplastic siloxane copolymer. The siloxane copolymer provides good adhesion, freedom from water absorption, and yet can be reworked either in the field or during recycling of the solar cell components. | 02-25-2010 |
20100086783 | REDISPERSIBLE CORE-SHELL POLYMERS AND A PROCESS FOR PREPARING THEM - Redispersible core/shell elastomeric particles are prepared by a process wherein a silicone elastomer core is covered with a second silicone shell, followed by an organic polymer shell. | 04-08-2010 |
20100233489 | FLUOROPOLYMER-SILICON COMPOUNDS AND METHOD FOR PRODUCTION - Composites of a fluoropolymer and an organopolysiloxane/polyurethane/polyurea adhesive exhibit strong adhesion while also offering desirable handling properties. | 09-16-2010 |
20100305273 | REACTION RESIN COMPRISING CORE-SHELL PARTICLES AND METHOD FOR THE PRODUCTION THEREOF AND THE USE THEREOF - Thermoset polymer systems are toughened without compromising other polymer properties by including 0.5 to 50 weight percent of 0.001 to 0.4 μm monodisperse core/shell polymers having at least an inner core of a silicone polymer and an outer core of organopolymer. | 12-02-2010 |
20110009572 | POLYMER BLENDS CONTAINING POLYDIORGANOSILOXANE UREA COPOLYMERS - Polymer blends containing organopolysiloxane-polymer-polyurethane copolymers and thermoplastic polymers bearing epoxy, carboxylic acid, carboxylic acid ester, or carboxylic acid anhydride groups exhibit enhanced physical properties. | 01-13-2011 |
20110076795 | MIXTURES OF ORGANOPOLYSILOXANE COPOLYMERS - Organopolysiloxane/polyuria/polyurethane block copolymers containing a compatible UV stabilizer are transparent and resistant to degradation. | 03-31-2011 |
