- Title
Morphology of ABA Block Polymers.

- Abstract
MICROPHASE separation is believed to occur in many block copolymers. In interpreting the mechanical properties of block copolymers of the type Ax By Ax, where Ax and By are blocks having x repeat units of type A and y repeat units of type B respectively, it has been suggested that when y is much greater than x the Ax blocks aggregate to form spherical domains in a matrix composed of By blocks1. Partial support for this model has recently been obtained from electron microscopy studies carried out on copolymers in which the outer blocks were polystyrene and the central block polybutadiene.
