Nematogenic Aromatic Block Copolymers of Rigid and Flexible Units. II. Phase Equilibria.

Abstract

Chemically dissimilar polymers are generally incompatible, and this incompatibility is even more marked for a coiling polymer in the nematic phase of a more rigid polymer, Phase diagrams were determined for the aromatic block copolymers of rigid and flexible units described in a previous paper. Flexible blocks enter the nematic phase formed by the rigid units. The flexible homopolymer also enters the nematic phase, but this seems to be due to the formation of an adduct involving the flexible and rigid polymers when both are polymerized simultaneously.
