ABSTRACT:
A process for preparing a graft polymer by subjecting a cyclic ester to ring-opening polymerization in the presence of a cellulose derivative in the presence of a ring-opening polymerization catalyst for the cyclic ester. The resulting graft polymer has high transparency, good film-formability and high solubility and can be suitably used as a novel polymer material.
