摘要：

The chain conformation and location of parts of a block polymer in a lamellar structure of diblock copolymers of styrene and 2-vinylpyridine were studied by small-angle neutron scattering. It was found that the chain adjacent to the junction between the two blocks is located near the boundary between domains and is contracted along the direction parallel to the lamellae to the same extent as a whole block chain with the same molecular weight, while the chain at the free end of block polymer is located in the middle of domain and is unperturbed. © 1990, American Chemical Society.
