WATER BORNE PRESSURE SENSITIVE ADHESIVE COMPOSITIONS DERIVED FROM COPOLYMERS OF HIGHER VINYL ESTERS. |
| 摘要 |
<p>The present invention is directed to improved aqueous based pressure sensitive adhesive emulsion polymers. Conventional emulsion based pressure sensitive adhesives are comprised of a copolymer comprised of polymerized units of acrylic esters and ethylenically unsaturated monomers, the copolymer a Tg of from -15 to -70 degree C. The improvement in the aqueous based, emulsion polymerized pressure sensitive adhesive resides in the incorporation of a vinyl C8-13 ester of a neo-acid into the copolymer present in the pressure sensitive adhesives. Such vinyl ester is formed from a mixture of propylene oligomers and such vinyl ester is represented by the chemical formula: (see formula).</p> |
