Abstract
PURPOSE: To provide a transparent sheet or a container having excellent heat resistance and being suitable as a food package or the like by molding copolymerized polyester formed from a dicarboxylic acid component containing terephthalic acid at a content above a specified amount and specified diol component.
CONSTITUTION: A dicarboxylic acid component containing 60mol% or more, preferably 70mol% or more the terephthalic acid and a diol component containing 85W99mol% of aliphatic or alicyclic diol such as 1,3-propanediol or 1,4-cyclohexanedimethanol and 15W1mol% of 1,3-cyclohexanediol are subjected to esterification reaction or transesterification reaction and copolymerized polyester is formed by a heat polycondensation method or the like by using a catalyst. Subsequently, the obtained copolymerized polyester is molded to a sheet or a container by a melt molding method or the like.
