    摘要: Disclosed are polyester pellets made of a polyester which comprises dicarboxylic acid constituent units derived from dicarboxylic acids containing terephthalic acid and isophthalic acid and diol constituent units derived from diols containing ethylene glycol and 1,3-bis(2-hydroxyethoxy)benzene, and which has the properties: constituent units derived from terephthalic acid are 15 to 99.5% by mol and constituent units derived from isophthalic acid are 0.5 to 85% by mol, both based on the total amount of dicarboxylic acid isophthalic acid constituent units (i); constituent units derived from ethylene glycol are 25 to 99.5% by mol and constituent units derived from 1,3-bis(2-hydroxyethoxy)benzene are 0.5 to 75% by mol, both based on the total amount of the diol constituent units (ii); the intrinsic viscosity is in the range of 0.5 to 1.5 dl/g; and the melting point (Tm (°C.)), as measured by a differential scanning calorimeter, satisfies the formula [1/527−0.0017·ln(1−(mI+mB)/200)]−1−273

    摘要: A polyester polymer is a condensation product of a diol component and a dicarboxylic acid component, and the diol component (i) includes at least one tricyclo[5.2.1.02,6]decanedimethanol represented by the following formula (1): wherein two hydroxymethyl groups are bound to carbon atoms constituting tricyclo[5.2.1.02,6]decane ring and wherein each of carbon atoms constituting the ring may have at least one additional substituent; or (ii) the dicarboxylic acid component includes at least one tricyclo[5.2.1.02,6]decanedicarboxylic acid represented by the following formula (2): wherein two carboxyl groups are bound to carbon atoms constituting tricyclo[5.2.1.02,6]decane ring and wherein each of carbon atoms constituting the ring may have at least one additional substituent. The polyester polymer has an excellent formability in addition to a high heat resistance, low water absorption property, and satisfactory optical characteristics.
