  • Process for neutralizing crosslinked poly (acrylic acid)
    Patent number: 4888367
    Abstract: High polymer content compositions, containing the neutralized salt of a carboxyl-containing polymer suspended in an organic medium, are made by neutralizing the carboxyl-containing polymer in the presence of a neutralizing agent and an equal quantity of already neutralized polymer in an organic medium. These compositions are useful as thickeners and emulsifiers for aqueous solutions.
    Type: Grant

  • Method of forming a nonaqueous stable emulsion of rubber in polymerizable monomer, and the polymerization process and thermoplastic copolymers produced thereby
    Patent number: 4767822
    Abstract: A process for the production of a nonaqueous stable emulsion feedstock comprising a rubber, a block copolymer having at least one component miscible with the rubber and at least one component miscible with the monomer, and at least two unsaturated organic monomers capable of free radical polymerization is disclosed. At least one of the monomers must be miscible with the rubber and the mixture of the monomers is substantially a nonsolvent for the rubber. The block copolymer maintains the rubber or rubber-rich particles in emulsified form within the mixture of monomers. In general, the process comprises (1) mixing the rubber, block copolymer and at least a portion of the rubber miscible monomers to form a first nonaqueous solution, (2) mixing the remaining monomers and the remaining portion of the rubber miscible monomers to form a second solution, and (3) combining the two solutions to form the nonaqueous stable emulsion feedstock.
