| 主权项 | 1. A crystalline polyester resin, comprising a condensation polymerization product of: (i) a dicarboxylic acid component containing at least one compound selected from the group consisting of terephthalic acid and terephthalic acid derivatives; and (ii) a diol component containing at least one compound selected from the group consisting of 2-methyl-1,3-propanediol and derivatives of 2-methyl-1,3-propanediol, said crystalline polyester resin having a weight-average molecular weight as measured by gel permeation chromatography of 5000 to 50000, and a Young's modulus as measured by an ultramicro durometer at 25° C. of at least 2 GPa and a melting point of 60° C. to 125° C. | ||
