Abstract
A polyamideimide copolymer which is an imide of a polyamic acid resulting from copolymerizing an aromatic diamine monomer, an aromatic dianhydride monomer, and an aromatic dicarbonyl monomer and a colorless and transparent polyamideimide film including the polyamideimide copolymer. The polyamideimide copolymer according to the present disclosure makes it possible to provide a polyamideimide film exhibiting excellent scratch resistance while being colorless and transparent.
Claims6
A polyamideimide copolymer, which is an imide of a polyamic acid resulting from copolymerizing an aromatic diamine monomer, an aromatic dianhydride monomer, and an aromatic dicarbonyl monomer,
- wherein the aromatic dicarbonyl monomer is contained in an amount of 65 to 90 mol % based on the total moles of the aromatic dianhydride monomer and the aromatic dicarbonyl monomer,
- wherein the aromatic dicarbonyl monomer is contained in an amount of 40 to 55 mol % based on the total moles of the aromatic diamine monomer and the aromatic dicarbonyl monomer, and
- wherein the aromatic dicarbonyl monomer consists of 10 to 29 mol % of isophthaloyl chloride and 71 to 90 mol % of terephthaloyl chloride.
