John Langley, David Holroyd: Production of paper and paperboard. Allied Colloids, Ostrolenk Faber Gerb & Soffen, June 28, 1988: US04753710 (172 worldwide citation)

Paper or paper board is made by passing an aqueous cellulosic suspension through a centriscreen or other shear device and then draining the purified suspension, and an improved combination of retention, drainage, drying and formation is achieved by adding to the suspension an excess of high molecula ...

Brian Dymond, John Langley, Malcolm Hawe: Polymeric compositions and methods of using them. Allied Colloids, Ostrolenk Faber Gerb & Soffen, June 2, 1987: US04670501 (115 worldwide citation)

Water-immiscible liquids, for example oil-based drilling fluids, are thickened by the addition of an aqueous dispersion of polymeric particles that are water-insoluble, and insoluble but swellable polymer, in the water immiscible liquid. The particles have a unswollen average diameter of less than 1 ...

Michael B Heard: Polymeric particles, their manufacture and uses. Allied Colloids, Ostrolenk Faber Gerb & Soffen, July 18, 1989: US04849484 (108 worldwide citation)

A slow release composition comprises particles of a cross linked polymeric matrix in which a water soluble reagent is dispersed, and the reagent is anionic, generally being a low molecular weight anionic water soluble polymer, and the matrix is a cationic, highly cross linked, polymer formed from a ...

David Farrar, John G Langley, Adrian S Allen: Water soluble polymeric compositions. Allied Colloids, Ostrolenk Faber Gerb & Soffen, May 30, 1989: US04835206 (101 worldwide citation)

A homogenous blend is formed of different water soluble polymer types, for instance of particular addition and condensation polymers, by forming one of the polymers from its monomeric starting material by polymerisation in a solution of the other polyer. The resultant solution has a concentration of ...

Farrar David, Hawe Malcolm: Polymeric thickeners and their production.. Allied Colloids, April 1, 1987: EP0216479-A1 (90 worldwide citation)

Polymers are made by polymerisation of an ionic monomer such as methacrylic acid or dialkylaminoalkyl (meth)acrylate or -acrylamtide and/or a substantially non-ionic monomer, optionally a cross linking agent, and an allyl ether of the formula CH2=CR min CH2OAmBnApR where R min is hydrogen or methyl, ...

This invention relates to aqueous acidic solutions which are thickened by cationic polymer, the polymer being added to the solution in the form of particles below 10 .mu.m in size. The useful cationic polymers are formed from a water soluble cationic ethylenically unsaturated monomer or blend of mon ...

Brian Dymond, John Langley, Malcolm Hawe: Polymeric compositions and methods of using them. Allied Colloids, Ostrolenk Faber Gerb & Soffen, October 11, 1988: US04777200 (78 worldwide citation)

Dispersions in water-immiscible liquid of water-soluble or water-swellable polymer particles are stabilized by use of an aqueous emulsion of water insoluble viscosifying polymer particles that are swellable or soluble in the water-immiscible liquid. After adding the emulsion to the water-immiscible ...
