Abstract
PURPOSE: To obtain a film having high Young's modulus and strength, by forming the film with a polyester, composed of p-hydroxybenzoic acid residue, tere-or isophthalic acid residue and an aromatic diol residue.
CONSTITUTION: A film, comprising p-hydroxybenzoic acid residue, terephthalic or isophthalic acid residue and an aromatic diol residue of formula I, II and III (wherein X:Y and X:Z are 80:20W50:50; Y:Z is 10:15W15:10; n is 0.1; carbonyl in formula II is at meta-or para-position to each other; hydroxy group in formula III is at meta-or para-position to each other, when N=0, and at meta- or meta-position to phenyl group when N=1). Its Young's moduli and strength in the direction of a machine axis, and in the direction perpendicular to the axis, are respectively ≥200kg/mm2 and ≥5kg/mm2, and the product of said both moduli is ≥8×104(kg/mm2)2.
