Abstract
A method for producing a liquid-crystal polyester processed product having improved adhesion, includes a preliminary step of providing a formed body of a liquid-crystal polyester resin including a repeating unit represented by general formula (1); a step (I) of performing an oxidation treatment on a surface of the liquid-crystal polyester resin formed body; and a step (II) of stacking a resin layer on the surface on which the oxidation treatment has been performed to produce a laminate.
Claims4
A method for producing a liquid-crystal polyester processed product, comprising:
- a preliminary step of providing a formed body of a liquid-crystal polyester resin including a repeating unit derived from 4-hydroxy-2-methylbenzoic acid, represented by the following formula,
- said preliminary step including obtaining the liquid-crystal polyester resin by polycondensation of the following components:
- (A) 4-hydroxy-2-methylbenzoic acid, and/or a derivative thereof, and
- (B) an aromatic hydroxycarboxylic acid other than component (A),
- wherein a content of component (A) is 5 mol % or more but 50 mol % or less relative to a total content of component (A) and component (B), followed by obtaining a formed body of the liquid-crystal polyester resin;
- a step (I) of performing an oxidation treatment on a surface of the liquid-crystal polyester resin formed body;
- and
- a step (II) of stacking a resin layer on the surface on which the oxidation treatment has been performed to produce a laminate.
