Abstract:
The inventive concepts provide methods of purifying a block copolymer and methods of forming a pattern using the same. The purifying method is performed using a first adsorbent. The first adsorbent has adsorbability with respect to a first polymer block having a molecular weight equal to or greater than a first average molecular weight. The purifying method further includes purifying a synthesized polymer using a second adsorbent. The second adsorbent interacts with a second polymer block.
