✦ Synopsis

Abstract

The conformation of diblock copolymer chains in a computer simulated homogeneous melt is analyzed distinguishing the separation of ends and the end‐to‐end vector orientation of individual chains. It is demonstrated that within the cigar‐like shapes of chains the blocks A and B are spatially separated along the cigar axis constituting concentration dipoles. Consequences of such concentration correlations for the light scattering are discussed. An extra contribution to the depolarized light scattering resulting from the β€œform birefringence” of individual chains is postulated.

## Abstract We consider diblock copolymer melts in the regime that the volume fraction of one component is small. In this regime microphase separation results in the formation of a large number of small spherical particles. We present here a simple method to derive effective evolution equations for
