Beschreibung
Zusammenfassung:	PURPOSE:To obtain the titled adhesive suitable for tacky adhesive tape having excellent adhesion and reliability, by subjecting an acrylic acid higher alkyl ester, an acrylonitrile and an unsaturated carboxylic acid, etc., to emulsion polymerization to give an emulsion having specific physical properties and blending the emulsion with a polyglycidyl compound. CONSTITUTION:A monomer mixture consisting of 80-99wt% acrylic acid alkyl ester containing 8-12C alkyl group, 0.5-18wt% (meth)acrylonitrile, 0.1-10wt% alpha,beta-unsaturated carboxylic acid and 0-10wt% another copolymerizable monomer is subjected to emulsion polymerization in water to give an aqueous copolymer emulsion having 5X10 -40X10 number-average molecular weight,
