  • System for determining stretch characteristics of thermoplastic articles
    Patent number: 5438878
    Abstract: Disclosed are a method and apparatus for determining the stretching characteristics of thermoplastic articles such as bottles on a consistently accurate basis by making an initial measurement such as dimension or volume, stretching the article to the onset of strain hardening, and correlating the measurements to a physical property such as inherent viscosity, intrinsic viscosity or molecular weight of the thermoplastic article.
    Type: Grant
    Filed: May 31, 1994
    Date of Patent: August 8, 1995
    Assignee: Eastman Chemical Company
    Inventor: Max L. Carroll, Jr.

  • Polyester-polyolefin blend film or coating composition
    Patent number: 4046837
    Abstract: Poly(tetramethylene terephthalate) having an inherent viscosity of from about 0.6 to about 1.4 is modified by the addition of from about 5 to about 35 percent by weight of polyethylene having a density of about 0.918 gm./cc. and a melt index from about 0.1 to about 10.0 to provide an extrusion film or coating composition especially for the coating of substrates at very high line speeds, while resulting in consistent coating characteristics.
