Blends of high Tg polymer emulsions and pressure sensitive adhesive polymer emulsions useful as pressure sensitive adhesives

摘要

A pressure sensitive adhesive with a good balance of adhesive and cohesive properties, produced by blending a high Tg polymer emulsion with an aqueous pressure sensitive adhesive polymer emulsion. The high Tg polymer has a Tg of 30 °C to 300 °C, a number average particle size (Dn) of 80 to 1000 nm, and a particle size distribution in which less than 25 % of the particles are less than 80 nm and less than 25 % of the particles are more than 1000 nm.
