Patent number: 4634451Abstract: Aqueous carbonaceous mixtures such as water slurries of solid particulate carbonaceous materials having reduced viscosity, a stabilized network of carbonaceous materials in water and improved pumpability are obtained by using a condensation product of an aldehyde in aldehyde liberating composition, ketone and sulfur dioxide in a sulfur dioxide liberating composition as dispersant, the dispersant being present in an amount sufficient to reduce viscosity of the slurry, stabilize the network of carbonaceous materials in water and improve pumpability. An improved process for the condensation product is disclosed.Type: GrantFiled: May 10, 1985Date of Patent: January 6, 1987Assignee: Diamond Shamrock Chemicals CompanyInventors: Stanley A.

An example of a copolymer is a copolymer of (1) a nonionic vinyl monomer such as acrylamide or methacrylamide and (2) an amphoteric vinyl monomer such as a reaction product of dimethylaminoethyl methacrylate and monochloroacetic acid. An example of a terpolymer is a terpolymer of (1) a nonionic vinyl monomer such as acrylamide or methacrylamide, (2) an anionic vinyl monomer such as sodium acrylate and (3) a cationic vinyl monomer such as a triethyl ammonium ethyl methacrylate methosulfate salt.Type: GrantFiled: February 22, 1985Date of Patent: November 12, 1985Assignee: Diamond Shamrock Chemicals CompanyInventors: Stanley A.

Patent number: 4505833Abstract: Process for treating a clayey geological formation to prevent, inhibit or reduce swelling or migrating of clay particles in a formation by treating the formation with an effective amount of a quaternized oligomer which is the reaction product of a polyamine having a primary amino group and a tertiary amino group with a difunctional reactant to form a precondensate monomer which is then chain extended and quaternized by reaction with a dihalogenated hydrocarbon ether.A preferred oligomer is a product of:(I) about 1.0 mole of a precondensate which is the reaction product of(A) from about 2.0 to about 3.0 mole of a polyamine having a primary amino group and a tertiary amino group, the polyamine having a non-cyclic backbone containing between 1 and 6 carbon atoms, with(B) about 1.0 mole of a difunctional reactant which is a diester of a mixture of dicarboxylic acids such as adipic, glutaric and succinic acid, with(II) from about 1.0 to about 1.2 mole of a chain extender such as dichloroethylether.Type: GrantFiled: October 3, 1983Date of Patent: March 19, 1985Assignee: Diamond Shamrock Chemicals CompanyInventors: Stanley A.

Patent number: 3960987Abstract: Propylene, for example, is polymerized with crystalline TiCl.sub.3 --AlCl.sub.3 and diethylaluminum monochloride catalyst at a rate of at least 300 lbs. polymer/lb. catalyst/hr. based on TiCl.sub.3 with partial H.sub.2 pressure of about 150 to about 1000 psi and sufficient total pressure to maintain propylene in liquid form. The resulting propylene homopolymer, while still containing active catalyst residues, is then reacted further with at least one additional alpha-olefin, preferably ethylene or ethylene-containing alpha-olefin mixtures in suitable amounts. The resulting waxy block copolymer has a melt flow of 40 to 400 as determined by ASTM-D-1238-62T at 230.degree.C.Type: GrantFiled: September 23, 1974Date of Patent: June 1, 1976Assignee: Dart Industries Inc.Inventors: Joseph M.
