The present invention relates to an acrylic pressure sensitive adhesive composition comprising acrylic copolymers wherein the gel fraction represented by the specific formula (1) is 45 to 75%, the swelling ratio represented by the specific formula (2) is 5 to 20, and the weight average molecular weight of non-crosslinking polymer contained in a pressure sensitive adhesive prepared from the pressure sensitive adhesive composition sol eluted from the adhesive prepared by the composition with ethyl acetate is at least 300,000.

Acrylic pressure-sensitive adhesive composition

Disclosed is an adjuvant for use in simultaneous polishing of a cationically charged material and an anionically charged material, which forms a adsorption layer on the cationically charged material in order to increase the polishing selectivity of the anionically charged material to cationically charged material, wherein the adjuvant comprises a polyelectrolyte salt containing: (a) a graft type polyelectrolyte that has a weight average molecular weight of 1,000&#x2dc;20,000 and comprises a backbone and a side chain; and (b) a basic material. CMP (chemical mechanical polishing) slurry comprising the above adjuvant and abrasive particles is also disclosed.
