US Patent:
58721819, Feb 16, 1999
Filed:
Jul 9, 1997
Appl. No.:
8/890436
Inventors:
Christian Leonard Daniels - Macungie PA
Randolph J. Lorenz - Wyomissing PA
Richard Joseph Goddard - Souderton PA
Assignee:
Air Products and Chemicals, Inc. - Allentown PA
International Classification:
C08L 3102
US Classification:
524563
Abstract:
Improved aqueous emulsion vinyl acetate-ethylene (VAE) polymer adhesives for use in packaging applications and on difficult to bond surfaces such as polyethylene, poly(ethylene terephthalate), and oriented polypropylene. The VAE polymers contain about 55-80 wt % vinyl acetate, 15-45 wt % ethylene, and 0-30 wt % of one or more additional ethylenically unsaturated copolymerizable monomer, based on the total weight of monomers. Cast films of the VAE emulsion polymers of this invention should have a tensile storage modulus (test frequency of 6. 28 rad/sec) within the area encompassed by the following data points: 1. times. 10. sup. 5 and 2. times. 10. sup. 7 dynes/cm. sup. 2 at 23. degree. C. , and 1. times. 10. sup. 3 and 2. times. 10. sup. 6 dynes/cm. sup. 2 at 70. degree. C. ; preferably within the area encompassed by the following data points: 1. times. 10. sup. 6 and 1. 5. times. 10. sup.
