Lloyd F. Barringer, Jr. 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).

  • Polymers having enhanced hydrophilicity and thermal regulated properties and process of producing the same
    Patent number: 5614598
    Abstract: This invention relates to polymers having enhanced hydrophilicity and thermal regulative properties. Exemplary polymers include aliphatic polyamide polymers and polyester polymers. The polymer has bonded thereto a hydrophilic polysiloxane having an affinity for the polymer and having a molecular weight greater than about 1000 g/mol preferably greater than about 2000 g/mol, and preferably greater than about 4000 g/mol. The polymer has substantially no polymerization with the hydrophilic polysiloxane. Alternatively, an aliphatic polyamide polymer is provided having enhanced hydrophilicity and thermal regulative properties. The polymer has bonded thereto an anionic hydrophilic polysiloxane having an affinity for the aliphatic polyamide polymer. The aliphatic polyamide polymer has substantially no polymerization with the anionic hydrophilic siloxane.
    Type: Grant

  • Polymers having enhanced durable hydrophilicity and durable rewetting properties and process of producing the same
    Patent number: 5408012
    Abstract: This invention relates to polymers having enhanced durable hydrophilicity and rewetting properties. The polymer has bonded thereto a hydrophilic copolymer. The copolymer comprises the reaction product of a primary hydroxylate having rewetting properties and a silane. The aliphatic polyamide or polyester polymer has an affinity for the hydrophilic copolymer and has substantially no polymerization with the hydrophilic copolymer. The present invention also provides a process of treating polymers to impart hydrophilicity and rewetting properties.
