Patents by Inventor Edwin L. Sukman

Edwin L. Sukman has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Tris(aryl)alkyl phosphonium halides and pesticidal compositions thereof
    Patent number: 4264593
    Abstract: Tri(phenyl)alkyl phosphonium halides wherein the phenyl groups contain a long chain or sterically hindered alkyl group are novel and exhibit efficacious levels of fungicidal and bacteriocidal activity. The presence of the alkyl substituent eliminates or significantly reduces the phytotoxicity that characterizes the corresponding unsubstituted phosphonium compounds.
    Type: Grant
    Filed: October 31, 1979
    Date of Patent: April 28, 1981
    Assignee: M&T Chemicals, Inc.
    Inventor: Edwin L. Sukman
  • Insecticidal and ovicidal method
    Patent number: 4101655
    Abstract: Insects and acarids are effectively controlled by applying to these organisms, their eggs or their habitat certain tertiary bis(halophenyl)-phosphines, phosphine oxides and phosphine sulfides. These compounds kill the adult, nymph and egg stages. At lower dose levels the compounds are effective chemosterilants for eggs of insects and acarids.
    Type: Grant

    Date of Patent: July 18, 1978
    Assignee: M & T Chemicals Inc.
    Inventor: Edwin L. Sukman
  • Additive-containing fibers
    Patent number: 4055702
    Abstract: Additives can be permanently incorporated into melt spun fibers by cold drawing the fibers under conditions that generate a network of interconnecting microvoids within the fiber. The microvoids are formed in the presence of specified liquid or vapor media which fill the microvoid network. The temperature of the medium is below the effective glass transition temperature of the fibers containing said medium. The additive is either present in said medium or is applied to drawn fibers containing said medium.
    Type: Grant
    Filed: December 2, 1975
    Date of Patent: October 25, 1977
    Assignee: M & T Chemicals Inc.

  • Method for permanently and uniformly incorporating an additive into an undrawn fiber
    Patent number: 4001367
    Abstract: Additives can be permanently incorporated into melt spun fibers by cold drawing the fibers under conditions that generate a network of interconnecting microvoids within the fiber. The microvoids are formed concurrently with the drawing of the fiber in a non-solvent liquid or vapor media, which media fills the microvoid network. The temperature of the medium is below the effective glass transition temperature of the fibers containing said medium. The additive is either present in said medium or is applied to drawn fibers containing said medium.
    Type: Grant
    Filed: November 7, 1974
    Date of Patent: January 4, 1977
    Assignee: M & T Chemicals Inc.

  • Method for controlling acarids with phosphine oxides
    Patent number: 3989824
    Abstract: Acarids, including spider mites, are effectively controlled by applying to the acarids, their habitat or both certain tertiary bis(halophenyl)phosphines, phosphine oxides and phosphine sulfides. These compounds kill adult and nymph acarids in addition to their eggs.
    Type: Grant

  • Flame retardant compositions derived from difunctional carboxylic acids containing a halogenated thiophere ring and methods for their preparation
    Patent number: 3970598
    Abstract: Flame retardant synthetic polyesters contain repeating units or side chains derived from mono- or dihalogenated dicarboxylic acids wherein the carboxylic acid groups are bonded directly to different carbon atoms of a thiophene ring structure.
