Abstract

PURPOSE: A polyester including titanium oxide that contains a specific amount of P is melt formed to produce delustered polyester thin films which reduce the damage of equipment used in processing.
CONSTITUTION: Difunctional carboxylic acids containing more than 75 mol% of terephthalic acid or their ester-forming derivatives, diols containing more than 75 mol% of ethylene glycol or their ester-forming derivatives that include a fine powder of titanium oxide containing more than 0.25 wt% of P (calculated as P2O5) as a deluster in such an amount that the content becomes 0.01W3.0 wt% in polyester are heated to effect the reaction and form diol esters of difunctional carboxylic acids and/or their oligomers. Then, these esters or oligomers are subjected to polycondensation reaction under heating and reduced pressure to give a polyester containing more than 75 mol% of ehylene terephthalate as recurring structural units, which is then melt formed into thin films of 1W100μm thickness.
