Zusammenfassung:	A process for production of an acryloyloxy- or methacryloyloxy-terminated polyester is described, which comprises reacting a specific hydroxy-terminated polyester with acrylic acid or methacrylic acid, wherein the hydroxy-terminated polyester comprises (a) a dicarboxylic acid unit comprising about 10 to about 80 mol % of a terephthalic acid unit and about 90 to about 20 mol % of another dicarboxylic acid unit and (b) a dihydric alcohol unit containing about 30 mol % or more of a dihydric alcohol unit containing 3 or more carbon atoms and having a number average molecular weight of about 400 to about 5,000.
