Small-angle x-ray-scattering study of ordering kinetics in a block copolymer

Abstract
The kinetics of microphase separation and ordering of a diblock copolymer onto a lattice has been studied using time-resolved high-resolution small-angle x-ray scattering. The measurements show rapid formation of spherical domains after quenching and a subsequent ordering of the spheres. The results are discussed within the framework of simple models for nucleation and crystalli- zation.
