Estimating the term…
A polyester composition with a polymer component which contains 99.8-60 wt % of a polyester with a terminal carboxyl group concentration of not more than 10 equivalents/10.sup.6 g (A) and 0.2-40 wt % of a thermoplastic polymer containing no fluorine atoms (B), and which also includes 0.005-1.5 wt % of unreacted carbodiimide compound (C), polyester monofilaments obtained from the composition, an industrial fabric and paper drier canvas which employ the polyester monofilaments, and a rubber mold reinforced with the polyester monofilaments. The composition is obtained by kneading in the polyester either after or during the process of melting and kneading the thermoplastic polymer containing no fluorine atoms and the carbodiimide compound, and the composition is spun, drawn and thermoset to obtain polyester monofilaments.
A polyester composition consisting essentially of:
A process for producing a polyester composition whose polymer component contains 99.8-60 wt % of a polyester with a terminal carboxyl group concentration of not more than 10 equivalents/10.sup.6 g (A) and 0.2-40 wt % of a thermoplastic polymer containing no fluorine atoms (B), and whose polymer component also includes 0.005-1.5 wt % of unreacted carbodiimide compound (C), which method comprises melting and kneading the polyester either after or during the process of melting and kneading the thermoplastic polymer containing no fluorine atoms and the carbodiimide compound.
