| Abstract: | Terephthalic acid/ethylene glycol/1,4-cyclohexanedimethanol copolymer(PETG) for plate materials was prepared from dimethyl terephthalate or terephthalic acid, ethylene glycol and self-made 1,4-cyclohexanedimethanol with antimony triacetate as catalyst and zinc acetate as additive. The optimal copolycondensation conditions were investigated. The results showed that by using triethyl phosphate as stabilizer, the modified copolyesters PETG could be prepared by conventional techniques and the inherent viscosity of the product was 0. 69 dL/g. The primary properties of the extruded plate were tested by extrusion rheameter. |
