Abstract

Pseudo network polymer is characterized by a network of linear segments which is composed of recurring units of a multivalent branching moiety, a chain-defining moiety, and a coupling moiety. The polymer may be formed into film, fiber and molded articles which exhibit improved mechanical properties in the transverse direction.
