Abstract

PURPOSE: A polyester containing a sulfonate metal salt as a structural unit is made into a melted sheet and solidified with cooling by the electrostatic pinning method, thus producing a film with smoothness at the surfaces and high transparency through high-speed process.
CONSTITUTION: (A) A terephthalic acid polyester containing 0.01W2.5mol%, based on the dicarboxylic acid components in the whole polymer, of a polyester- forming monomer bearing sulfonate metal salt groups or (B) a mixture of a polyester containing sulfonate metal salt groups with a sulfonate-free terephtalic acid polyester where the content of the sulfonate metal salt group is 0.01W2.5mol% based on the dibasic acid component in the whole polyester structural units is melt extruded into a film. Then, an electric charge is applied to the film by applying an electric field and the charged film is stuck to the cooling metal roll or conveying metal belt and solidified. The resultant film is stretched mono- or biaxially.
