Abstract
In the present invention, the polymer composition is produced by polymerizing an anionically or cationically polymerizable monomer in the presence of a highly syndiotactic styrenic polymer and optionally a rubber-like polymer. The polymer composition thus obtained is improved in its solvent resistance without using any particular compatibilizer and has a good moldability.
