43 POLYESTER COMPOSITION ABSTRACT OF THE INVENTION As an outline of the invention of the present inventors, the gist of the present invention resides in the following: A polyester composition comprising: (A) 100 parts by weight of a substantially linear polyester comprising, as the main constituent unit, ethylene terephthalate; (B) 0.05 to 15 parts by weight of a crystallization promotor; and (C) 0.1 to 15 parts by weight of at least one plasticizer selected from the group consisting of (C1), (C2), (C3) and (C4) which are defined as follows: (C1) a condensation product of a compound of the formula (I): (HQ - R)2S (I) wherein two R groups may be the same as or different from each other and represent a hydrocarbon group selected from the group consisting of aliphatic, alicyclic, and aromatic hydrocarbon groups and any combination thereof, and two Q groups may be the same as or different from each other and represent oxygen or sulfur, with an organic compound contain- ing two alcoholic or phenolic hydroxyl groups: (C2) an ester compound derived from an organic acid and a compound selected from the group consisting of compounds of the above mentioned formula (I) and the condensation products (C1). 44 (C3) an ether compound derived from a compound selected from the group consisting of com- pounds of the above-mentioned formula (I) and the condensation products (C1) and a compound selected from the group consisting of monohydric alcohols and monohydric phenols. (C4) a modified polyolefin wax selected from oxidized polyolefin waxes, unsaturated carboxylic acid or its derivative graft-modified polyolefin waxes, unsaturated epoxy compound- modified polyolefin waxes, unsaturated silane compound-modified polyolefin waxes, and styrene type monomer-modified olefin waxes.
