Chain dimensions of the polystyrene-d8 parts of a styrene-ds-2-vinylpyridine block copolymer (DP-33) and a styrene-da-styrene-hs block copolymer (DH-44), both with 50:50 compositions, were measured in dilute solutions of pyridine (a common good solvent) benzene (a selective solvent ) and methyl ethyl ketone (a poor solvent) by small-angle neutron scattering. The conformation of one block chain within a diblock copolymer is not affected by the existence of another block chain, regardless of the solvent power at least when the composition of the diblock copolymer is 50: 50, and the molecular weight is not high
