摘要: A suspension may be flocculated using a water soluble substantially linear polymer having a single point intrinsic viscosity above 3 and that is a copolymer of two or more ethylenically unsaturated monomers including at least 0.5% by weight of monomer carrying pendant hydrophobic groups. The cationic polymers are novel. Preferred polymers are those in which the hydrophobic group is introduced as an allyl ether.

摘要: Water soluble, substantially linear, polymers having single point intrinsic viscosity above about 3 are formed from an ethylenically unsaturated monomer that includes a group --B.sub.n A.sub.m R where A is propoxy or butoxy, B is ethoxy, n is zero or an integer of 2 to 100 and m is zero or an integer less than n, and R is a hydrophobic group of at least 8 carbon atoms and comonomer selected from non-ionic monomers and dialkylamino alkyl (meth) -acrylates or -acrylamides wherein at least one of the monomers is tertiary amine acid addition or quaternary ammonium salt. The resultant water soluble, high molecular weight, cationic polymers are useful as flocculants and as viscosifiers of aqueous acid solutions such as downhole acid stimulation fluids.

摘要: A concentrate composition, that can be diluted with water to form an aqueous size for cellulosic fibres, comprises a substantially anhydrous dispersion of polyelectrolyte particles in a non-aqueous liquid comprising a reactive size, and is made by forming a dispersion in a hydrophobic liquid of the polyelectrolyte particles while they are swollen by water, azeotroping the dispersion and adding the size to the hydrophoboic liquid. If the size is a liquid size, the hydrophobic liquid may be removed from the composition. The dispersion of swollen polyelectrolyte particles in the hydrophobic liquid can be amde by dispersing a solution of polyelectrolyte in the liquid but is preferably made by reverse phase polymerization.

摘要: A new process for producing allyl ethers, usually C.sub.8-30 alkyl (CH.sub.2 CH.sub.2 O).sub.5-100 allyl ether, by forming a solution of an alcohol, usually a surfactant alcohol, in a solvent capable of forming an azeotrope with water, azeotroping the mixture to remove substantially all the water, adding an alkalimetal alkoxide, usually sodium methoxide, removing the alkanol formed, usually by azeotroping with the solvent, adding a halide, usually allyl chloride, and recovering the allyl ether. The ethers are useful as monomers, for example to produce polymers by copolymerising with copolymerisable ethylenically unsaturated comonomers for a wide range of applications.

摘要: Concentrated (e.g. above 72% by weight) dispersions of calcium carbonate ground to a particle size such that at least 87% by weight of the particles are less than 2 .mu.m in size have a tendency to gel on standing. In the invention this tendency is minimized or eliminated by using, as dispersing agent, a copolymer of from 5 to 75% by weight AMPS and 95 to 25% by weight acrylic acid, or a water soluble salt thereof, having a molecular weight in the range 1000 to 20,000.

摘要: This invention relates to fabric conditioning formulations containing as thickeners a cross-linked cationic polymer of an ethylenically unsaturated monomer or blend of monomers, wherein the cross-linking agent is 5-45 ppm of a cross-linking agent comprising polyethylenic functions. An example of such a cross-linking agent is methylene bisacrylamide. Such thickeners do not contribute to the opacity of the formulations and have a relatively good viscosity stability.

摘要: A dispersing agent for particles in aqueous media comprises a copolymer formed from ethyleneically unsaturated monomers including a water-soluble monomer and a monomer carying a pendant group A.sub.m B.sub.n A.sub.p R in which B is ethyleneoxy and n is at least 2, m and p are each generally 0 and R is a hydrophobic group, generally a C.sub.12-18 alkyl group or alkaryl group. The polymers generally have molecular weights in the range 500-100,000. The dispersants are particularly useful for suspending hydrophobic particles in aqueous media, for example to produce coal slurries, or to suspend hydrophilic particles in aqueous media having high electrolyte concentrations, for example for producing paints and, particularly, drilling muds formed in sea water.
