    Inventors: Winston J. Jackson, Jr., Herbert F. Kuhfuss
  • Copolyester prepared from an acyloxybenzoic acid and polyethylene terephthalate modified with p-hydroxyethoxybenzoic acid
    Patent number: 4035356
    Abstract: Disclosed is a copolyester comprised of the following divalent radicals: ##STR1## wherein the range of radical (C) is from about 50 to about 80 mole percent, based on the total moles of (A) and (C) combined and the range of radical (D) is from about 20 to about 70 mole percent, based on the total moles of (A) and (D) combined. The copolyesters of this invention are prepared by a process comprised of two steps. The first step comprises forming a fragmented polyester by acidolysis of a starting polyester with an acyloxybenzoic acid. The second step comprises increasing the inherent viscosity of the fragmented polyester to form the copolyester of the invention. Radical (A) of the copolyester is contributed from the dicarboxylic acid portion of the starting polyester. Radical (B) of the copolyester is contributed from the ethylene glycol portion of the starting polyester.

  • Hot melt compositions
    Patent number: 3931073
    Abstract: Hot melt compositions having very low melt viscosity and high adhesive strength, especially to metals, are disclosed. The compositions include a copolyester derived from a glycol having from 2 to 10 carbon atoms, terephthalic acid and dimer acid, blended with an aliphatic hydrocarbon having a molecular weight of from about 250 to about 1200. The composition may be modified if desired by adding a small amount of a vinyl aromatic polymer.
    Type: Grant

  • Process for preparing containers using polyesters
    Patent number: T954004
    Abstract: disclosed is a process for preparing containers, such as bottles, using a polyester of terephthalic acid, ethylene glycol, and 1,4-cyclohexanedimethanol, wherein the 1,4-cyclohexanedimethanol is from 25 to 40 mole percent of the diol. A molten parison of such polyester is extruded and then expanded in a mold to form the desired container.
