Polyethylene terephthalate (PETP) has been prepared from dimethyl terephthalate and ethylene glycol in the presence of various amounts of a telechelic fluorinated macromer with methyl ester end‐groups using Ti(OBu)4 as the catalyst. The final products are heterophasic with a perfluoropolyether phase embedded in a PETP matrix. The effects of the fluorinated polymer on the reaction rates in the first and second stages of the reaction and on some properties (Tg, Tm, and contact angle) are discussed.

Abstract
Polyethylene terephthalate (PETP) has been prepared from dimethyl terephthalate and ethylene glycol in the presence of various amounts of a telechelic fluorinated macromer with methyl ester end‐groups using Ti(OBu)4 as the catalyst. The final products are heterophasic with a perfluoropolyether phase embedded in a PETP matrix. The effects of the fluorinated polymer on the reaction rates in the first and second stages of the reaction and on some properties (Tg, Tm, and contact angle) are discussed.
