John Y Chen: Gelatinous elastomer articles. Applied Elastomerics, August 9, 1994: US05336708 (177 worldwide citation)

Novel composites are formed from a low rigidity gelatinous elastomer composition of poly(styrene-ethylene-butylene-styrene) triblock copolymer and high levels of a plasticizing oil. The gelatinous elastomer composition is physically interlocked with an open cell sponge thereby displacing the air spa ...

Minnesota Mining and Manufacturing Company, Gary L Griswold, Walter N Kirn, Janice L Dowdall, October 24, 1995: US05461134 (130 worldwide citation)

Block copolymers having a repeating unit comprised of polysiloxane and urea segments are prepared by copolymerizing certain diaminopolysiloxanes with diisocyanates. The invention also provides novel diaminopolysiloxanes useful as precursors in the preparation of the block copolymers and a method of ...

Evert C Alsenz, William F Juptner, David F Macy: Angular rate sensor system. Piezoelectric Technology Investors, Knobbe Martens Olson & Bear, March 31, 1987: US04654663 (118 worldwide citation)

An angular rate sensor system is disclosed, consisting of a balanced resonant sensor. The sensor consists of a tuning fork of a piezoelectric material, preferably of quartz. The tines of the tuning fork are caused to vibrate electromechanically, for example, by impressing an alternating voltage on a ...

Flexible polymeric compositions are prepared by introducing sulfonate groups into a plastic polymer and plasticizing the ionomer so formed. Plasticization may be limited to plasticizing the amorphous backbone. Preferably the ionic domains of the ionomer are also plasticized using a plasticizer which ...

Solomon David Henry, Rizzardo Ezio, Cacioli Paul: New polymerization process and polymers produced thereby.. Commw Scient Ind Res, March 27, 1985: EP0135280-A2 (77 worldwide citation)

The present invention relates generally to improved processes for free radical polymerization, particularly to improved processes in which it is possible to control the growth steps of the polymerization to produce relatively short chain length homopolymers and copolymers, including block and graft ...

Wolfgang Wieder, Dieter Kuhlmann, Wolfgang Nentwig: Process for producing diene rubbers polymerized by means of Nd catalysts and exhibiting reduced cold flow and low intrinsic odor. Bayer, Connolly & Hutz, October 22, 1996: US05567784 (76 worldwide citation)

The production of diene rubbers polymerized by means of Nd catalysts and having reduced cold flow and low intrinsic odor is effected by the polymerization of diolefines adiabatically at temperatures of -20.degree. to 150.degree. C. in the presence of inert organic solvents and in the presence of met ...

Halasa Adel Farhan, Matrana Barry Allen, Robertson Wilcox Sylvia Eileen: Capping polydienes.. Goodyear Tire & Rubber, May 17, 1989: EP0316255-A2 (74 worldwide citation)

Polydiene rubbers are commonly compounded with carbon black in making a wide variety of rubber articles including tires, hoses and belts. It is generally desirable for the carbon black to be well dispersed throughout the polydiene in order to attain optimal physical properties. For instance, the tra ...

John E Cadotte: Reverse osmosis membrane. Midwest Research Institute, Merchant Gould Smith Edell Welter & Schmidt, March 31, 1981: US04259183 (70 worldwide citation)

A composite permselective membrane is prepared by reaction of a film or layer containing cycloaliphatic polyfunctional secondary amines with a triacyl halide or its mixture with a diacyl halide. The membrane is useful in separating components of fluid mixtures or solutions, such as the removal of sa ...
