Polymers containing nucleobases can have complementary multiple hydrogen bonding between nucleobases, and the strong multiple hydrogen bonding is expected to have an effect on phase behavior of block copolymer blends. For this purpose, we synthesize nucleobase-functionalized block copolymers polystyrene-b-poly(1-(4-vinylbenzyl)thymine) and polystyrene-b-poly(9-(4-vinylbenzyl)adenine) using reversible addition-fragmentation chain-transfer polymerization first. Then we characterized block copolymers using GPC and NMR, also we studied morphology of the block copolymers using transmission electron microscopy and small-angle X-ray scattering patterns. Additionally, when we change base pair from thymine-adenine to guanine-cytosine, strength of the hydrogen bonding can be controlled
