titleOfInvention | Dispersion stabilizer for coal-water slurry |
abstract | PURPOSE: To obtain a dispersant capable of providing a coal-water slurry which is excellent in flowability in a high concn. and shelf stability, by copolymerizing (meth)acrylic acid with a hydrophobic polymer having a thiol group at its end and dissolving the copolymer in water or an aq. alkaline soln. n CONSTITUTION: A monomer mixture comprising (meth)acrylic acid and, if necessary, 50mol% or less of other monomer is copolymerized with a hydrophobic polymer having a thiol group at its end to obtain a copolymer. The copolymer is dissolved in water or an aq. alkali soln. to obtain a block copolymer of the formula, wherein n is 1W2; P 1 is a hydrophobic polymer having a degree of polymerization of 2W500 and selected from among PS, polymethyl acrylate, polyoxypropylene, polyoxytetramethylene and polyvinyl versatate; and P 2 is a polymer having a degree of polymerization of 10W3,500 and comprising (meth) acrylic acid or its alkali (earth) metal or ammonium salt. 0.01W5.0wt% dispersion stabilizer contg. the aforesaid polymer as the effective ingredient is added to a water slurry having a concn. of 70wt% or more. n COPYRIGHT: (C)1987,JPO&Japio |
