Polyamic acid composition and preparation method thereof |
| abstract |
The present invention provides a polyamic acid composition comprising a diamine monomer and a dianhydride monomer in the molar ratio of 1:0.98 to 1:0.99, and satisfying Equation 1 below: [Equation 1] |[(V 1 - V 2 )/V 1 ] × 100| ≤ 15 (%), wherein V 1 represents a viscosity immediately after forming the polyamic acid composition on a support, and V 2 represents a viscosity after 1 hour at 25℃ after forming the polyamic acid composition on the support. |
