Title:
POLYESTER RESIN COMPOSITION AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2019/021787
Kind Code:
A1
Abstract:
[Problem] To provide: a polyester resin composition that has excellent heat resistance and hydrolysis resistance, while being suppressed in the amounts of a gel composition and a liner oligomer, which are generated during a melt molding or forming step; and a method for producing this polyester resin composition.
[Solution] The above-mentioned problem is solved by a polyester resin composition which is characterized by satisfying formulae (I)-(IV).
Amount of generated linear oligomer < 900 ppm (I)
∆COOH/COOH ≤ 2.0 (II)
5 ppm ≤ Mn content ≤ 40 ppm (III)
4 ppm ≤ Na content ≤ 40 ppm (IV)
