Abstract: The present invention provides a polyester resin composition having an excellent crystallization rate. The polyester resin composition includes (a) a polyester resin containing (b) a sulfonamide compound metal salt which has a structure represented by the following general formula (1): (in the formula (1), R and R' each independently represent a hydrogen atom, a halogen atom, an alkali metal atom, an amino group, an alkyl group which has 1 to 10 carbon atoms and which may be branched or substituted, an alkoxy group which has 1 to 10 carbon atoms and which may be branched or substituted, or a cyclic group which has 3 to 30 carbon atoms and which may be substituted; R and R' may be bonded together to form a cyclic group; n represents a number of 1 or 2).

Abstract: A process for producing a stabilized polymer by gas phase polymerization of a monomer having an ethylenically unsaturated bond, characterized in that at least one phenolic antioxidant represented by the general formula (I) which is masked by an organic aluminum is added to a catalyst system or polymerization system prior to or during the polymerization. (wherein R1 and R2 independently represent a hydrogen atom, an alkyl group having 1 to 9 carbon atoms, a cycloalkyl group or an arylalkyl group; X represents an alkylene group having 1 to 8 carbon atoms; R3 represents a hydrogen atom or an alkyl group having 1 to 8 carbon atoms; and R4 represents an alkyl group having 1 to 30 carbon atoms).
