실험 절차

Under an argon stream, 10 g of 1,4-bis(hydroxyethyl) terephthalate (BHET) prepared as described above in Example 1, 9.61 g of 4-dimethylaminopyridine (DMAP), and 70 mL of methylene chloride were placed in a 250 mL flask equipped with a funnel. The solution in the flask was cooled down to −40° C. with stirring, and a solution of 5.13 g of ethyl phosphorodichloridate (EOP) (distilled before use) in 20 mL of methylene chloride was added dropwise through the funnel. After addition was complete, the mixture was stirred at room temperature for four hours to form the homopolymer BHET-EOP.
