Joseph M. Sandri 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).

  • Polymerizable compositions comprising derivatives of mono-(alkylene ureido alkyl) ureas and bis-(alkylene ureido alkyl) ureas
    Patent number: 4429095
    Abstract: The invention provides new compounds which are cyclic alkylene ureas produced by the reaction of an alkylene urea selected from the group consisting of a mono-(alkylene ureido alkyl) urea, a bis-(alkylene ureido alkyl) urea, and mixtures thereof, with an unsaturated glycidyl ether or ester, such as allyl glycidyl ether. The new compounds are monomers which may be incorporated in aqueous emulsion polymer systems and are useful as wet adhesion promoters for latex paints.
    Type: Grant
    Filed: February 25, 1982
    Date of Patent: January 31, 1984
    Assignee: Alcolac Inc.
    Inventors: Joseph M. Sandri, John W. Calentine, Seymour M. Linder, Yves J. Billioux
  • Derivatives of aminoalkyl alkylene ureas and their use as wet adhesion promoters
    Patent number: 4426503
    Abstract: The invention provides new compounds which are cyclic alkylene ureas having hydroxyl and amine functionalities and which are produced by the reaction of an omega-amino alkyl alkylene urea, such as 2-aminoethyl ethylene urea, with an unsaturated glycidyl ether or ester, such as allyl glycidyl ether. The new compounds are monomers which may be incorporated in aqueous emulsion polymer systems and are useful as wet adhesion promoters for latex paints.
    Type: Grant
