Product 1

HCID 250594Cyclohexanedimethanol

Procedure

As a thermoplastic resin there was used a 5:4:1 (by mole) of terephthalic acid, bisphenol A-ethylene oxide adduct and linear polyester obtained from cyclohexane dimethanol (Tg: 62° C.; Mn: 4,500; Mw: 10,000). This thermoplastic resin was ground using a jet mill, and then classified using an air classifier to prepare a particulate material having d50 of 6 μm.
