Abstract
Quarter polymers(EBAG) were synthesized from 2-ethyl hexyl acrylate (2-EHA), n-butyl acrylate(BA), acrylic acid(AA) and glycidyl methacrylate (CMA) to prepare acrylic type pressure-sensitive adhesives (PSA''s) . The EBAG solutions were coated directly onto polyester film for the subsequent tape evaluation. Typical characteristics of the acrylic PSA''s are as follows; 1. Polymerization being carried out with 60℃ and Shrs was the obi tidal conditions of quarter polymerization based on glycidyl methacrylate in the range of monomer mole ratio such as 2-EHA 0.40∼0.70mo1, BA 0.35∼0.50mo1, AA 0.03mo1 and CMA 0.01mo1, 2. EBAC consisisting of 2-EHA 0.40∼0.70mo1, BA 0.35∼0.50mo1, AA 0.03mo1 and GMA 0.01mo1 gave such excellent performance as to be practically used for removable PSA''s. This EBAG are 220∼350g/inch in peel strength, more than 24hrs of holding Power, 4/32∼6/32 for tackiness and 80∼90℃ for heat resistance.
