MANUFACTURE OF LAMINATE

Japanese Patent JP3949216

B2

PROBLEM TO BE SOLVED: To provide a simple method for manufacturing a laminate of a low cost having excellent heat resistance, small dielectric constant, dielectric tangent and water absorption ratio with satisfactory external appearance.
SOLUTION: The method for manufacturing a laminate comprises the steps of melt extruding liquid crystal polyester resin composition containing copolymer having (A) liquid crystal polyester as a continuous phase and (B) copolymer having a functional group including reactivity with the polyester as a dispersed phase from a T-die, laminating it on woven fabric or nonwoven fabric made of fiber material containing organic fiber material and/or inorganic fiber material, and press bonding it. Further, the method may comprise the steps of melt extruding liquid crystal polyester resin composition containing (A) liquid crystal polyester as continuous phase and (B) copolymer having a functional group including reactivity with the polyester as a dispersed phase from a T-die, laminating it on woven fabric or nonwoven fabric made of organic fiber material and/or inorganic fiber material continuously supplied via a roll and metal foil, and press bonding it.
