  • Publication number: 20140170309
    Abstract: The invention relates to miscible blends of cellulose acylates, films made therefrom and methods of making the miscible blends of cellulose acylates and films made therefrom.
    Type: Application
    Filed: November 20, 2013
    Publication date: June 19, 2014
    Applicant: Eastman Chemical Company
    Inventor: Darryl Aubrey Godfrey
  • Publication number: 20140150691
    Abstract: The invention provides a way of using cellulose triacetate (CTA) made from softwood pulp to make films suitable for use in liquid crystal displays (LCDs). It has been surprisingly found that a combination of certain additives in the film casting dope and of metal and sulfur content of the CTA allow a softwood CTA to exhibit peeling characteristics from the casting substrate that are similar to those of lint-based CTA of similar sulfur content. The additives include a combination of acid scavengers and chelating agents.
    Type: Application

  • Patent number: 8007918
    Abstract: In one aspect, the invention relates to a composition comprising a cellulose ester and a high boiling plasticizer having a boiling point greater than 370° C., wherein the composition has a glass transition temperature (Tg) greater than a similar composition having triphenyl phosphate (TPP) plasticizer substituted for the high boiling plasticizer. The invention also related to articles and films made therefrom. This invention also relates to methods of making the compositions, articles and films.
    Type: Grant

  • Patent number: 5763516
    Abstract: Hot-melt adhesive compositions useful for packaging are disclosed. These hot-melt adhesive compositions are based on modified polyethylene and contain a linear, low density copolymer or terpolymer of ethylene and another alpha-olefin, a polyethylene graft copolymer, a tackifying resin, and a high-melting low viscosity wax. The hot-melt adhesive compositions disclosed herein produce very good adhesive bonds, even at high speed packaging conditions under a broad range of ambient packaging temperatures. These inventive adhesive compositions have a novel combination of good hot tack and good adhesive bond properties, even at extreme conditions.
