Patent number: 4085267Abstract: The invention relates to reduction of polymer buildup during the suspension polymerization of vinyl chloride, either alone or with other olefinically unsaturated monomers copolymerizable therewith. There is employed a particular combination of ingredients in the polymerization recipe, the essential features being the use of a water phase inhibitor and an oil phase inhibitor along with a substantially water-insoluble polymerization initiator and operating at a high pH. A multiplicity of charges may be polymerized in the reactor without opening the same.Type: GrantFiled: February 23, 1976Date of Patent: April 18, 1978Assignee: The B. F. Goodrich CompanyInventors: Marion George Morningstar, Robert Lewis Bowles

Patent number: 4074035Abstract: A continuous process for the preparation of gel-free interpolymers from monomers comprising one or more halomethylated vinyl aromatic compounds and one or more Type III monoolefins is characterized by the use of a solvent or mixture of solvents in which the reactants and the interpolymers are soluble; a soluble Lewis acid or Friedel-Crafts catalyst, especially an organo-Group IIIa element halide catalyst; a reaction temperature in the range of -120.degree. C to -20.degree. C; and a conversion of at least one of the monomers to interpolymer in excess of 85 percent. The interpolymers may be crosslinked with nucleophilic reagents to produce elastomeric compositions; quaternized with nitrogen, sulfur or phosphorous compounds to give self-emulsifying latices useful as surface coatings or converted to sulfonic or carboxylic derivatives for the preparation of ionomer resins.Type: GrantFiled: April 22, 1975Date of Patent: February 14, 1978Assignee: Exxon Research & Engineering Co.Inventors: Kenneth W. Powers, Irving Kuntz
