High cohesion waterborne pressure sensitive adhesives. |
摘要 |
<p>Waterborne pressure sensitive adhesive multipolymers exhibiting very high cohesive strength may be prepared by a two stage emulsion polymerization procedure (overpolymerization) in which the first stage is a low Tg (i.e., less than about -20 DEG C) copolymer having good adhesive properties, and the second stage is a high Tg (i.e., greater than about +25 DEG C) non-pressure sensitive homopolymer or copolymer and wherein the ratio of the first stage to the second stage are between 80 to 20 and 99 to 1.</p> |
