  • Multi-layer anti-fog compositions and processes for making same
    Patent number: 10654252
    Abstract: Multi-layer anti-fog compositions comprising an anti-fog layer and a protective layer. The anti-fog layer comprises cellulose acetate and a plasticizer and has opposing major planar surfaces. The protective layer has opposing major planar surfaces that are oriented substantially coplanar, at least in part, to the anti-fog layer that forms a multi-layered structure. The multi-layer anti-fog compositions further comprise one or more connectors, and at least one of the connectors extends through the multi-layered structure.
    Type: Grant
    Filed: May 18, 2017
    Date of Patent: May 19, 2020
    Assignee: CELANESE INTERNATIONAL CORPORATION

  • OXAZOLINE ANTI-CONDENSATION COMPOSITIONS, LAMINATES, AND PROCESSES FOR MAKING THE SAME
    Publication number: 20180105661
    Abstract: Anti-condensation compositions and laminates comprising a cellulosic material selected from a cellulose ester and a cellulose ether and a polymer of an oxazoline, and processes for making such anti-condensation compositions without the need for saponification. Such compositions have now been shown to exhibit extremely desirable anti-condensation characteristics, with a low degree of hazing and increased hardness.

  • ANTI-FOG CONSUMER PRODUCTS AND PROCESSES FOR MAKING SAME
    Publication number: 20160053152
    Abstract: A process for producing an anti-fog consumer product. The process comprises the steps of forming a precursor composition comprising cellulose acetate and plasticizer to yield a substantially rigid consumer product having an outer surface; and saponifying at least a portion of the substantially rigid consumer product to yield the anti-fog consumer product having a degree of substitution at the outer surface of less than 0.75.
