This invention is related to a polyester resin composition comprising:
a thermoplastic polyester resin and
a polyether compound-treated layered material having layers respectively exfoliated by one another,
which satisfies at least one of the conditions (i) to (v) given below:
(i) That said polyether compound has a hydroxyl value of not more than 30 mg KOH/g;
(ii) That said polyether compound has a cyclic hydrocarbon group:
(iii) That said polyester resin composition comprises a phosphorus-containing compound;
(iv) That said polyester resin composition comprises an epoxy-containing compound;
(v) That said polyester resin composition is obtainable by melt-kneading the thermoplastic polyester resin and the polyether compound-treated layered material having layers respectively exfoliated by one another and then treating the mixture for increasing the molecular weight of the polyester resin.
