Chain Conformations of Homopolymers Dissolved in a Microdomain of Diblock Copolymer

摘要: Single-chain conformations of styrene homopolymers dissolved in a polystyrene lamellar microdomain styrene-2-vinylpyridine diblock copolymer but were measured by SANS. The molecular weights the are 13.0K (L), 29.7K (M), and 76.7K (H), weight is 63.3K with 34.2K block. mixing ratios homopolymer/block blends 0.1/0.9 for L, 0.05/0.95 M, 0.01/0.99 H so as not to give rise macrophase separation. radii gyration direction parallel lamellae found be almost equal unperturbed dimension irrespective block
