Procedure

21.6 g (0.3 mol) of acrylic acid, 89.6 g (0.7 mol) of butyl acrylate, 3.28 g of 2,2′-azobisisobutyronitrile (AIBN) and 1200 ml of THF were introduced into a reactor and the atmosphere inside the container replaced with nitrogen. While stirring, heating was carried out for 8 hours at 60° C. and after the polymerization reaction had proceeded, the reaction mixture was added dropwise to 3000 ml of methanol and the polymer precipitated. Acrylic acid/butyl acrylate copolymer was obtained. When the Tg of this compound was measured by the DSC (Differential Scanning Calorimetry) method using a SSC5200/RDC220 (made by Seiko Denshi K.K.), it was found to be −23.5° C.
