Beschreibung
Zusammenfassung:	Preparing an aqueous emulsion of a pressure-sensitive adhesive based upon acrylic esters comprises effecting the polymerization of the pressure-sensitive adhesive formulation including ester(s) of (meth)acrylic acid in the presence of a styrene-containing polymer containing >=80 wt.% styrene. The styrene-containing polymer is incorporated in an amount of 5-30 wt.%. Preparing an aqueous emulsion of a pressure-sensitive adhesive based upon acrylic esters comprises effecting the polymerization of the pressure-sensitive adhesive formulation including ester(s) of (meth)acrylic acid in the presence of a styrene-containing polymer containing >=80 wt.% styrene. The styrene-containing polymer is incorporated in an amount of 5-30 wt.% based upon the combined weight of the pressure-sensitive adhesive formulation and the styrene-containing polymer. The acrylic ester-based adhesive has a good balance of adhesive and cohesive properties. The pressure-sensitive adhesive formulation comprises ester(s) of (meth)acrylic acid polymerized in the presence of water and an emulsifier.
