Abstrakt:

Dimethyl terephthalate (DMT) and dimethyl 2,6-naphthalate (DMN) copolymers with ethylene glycol (EG) were obtained by the melt polycondensation method. Melt points and glass transition temperatures were determined for selected copolymers using DSC. The evaluation of their thermal stability was based on TGA results. Changes in relative viscosities and the lowering of the mass of the polymer samples after long-lasting heating at 200 °C as well as changes in the melt viscosity after 1 h of heating at 290 °C were also investigated. Fire resistance was evaluated on the basis of the oxygen index (OI) tests. The mechanical properties and thermal stability of fibres obtained from DMT/DMN copolyesters were also determined.
