Abstract

Production process of polymers of the polyester series, especially polyolkylenic terephthalate, polyalkylone oxybenzoate or polyester or polyester-ether consisting mainly of polyalkylene terephthalate or polyalkylene oxybenzoate, characterized in that the polycondensation reaction is carried out in the presence of metallic antimony and titanium together, as a catalyst.
