ABSTRACT:
A suspension polymerization of a polymerizable monomer in the presence of an emulsion polymerization inhibitor is disclosed. The inhibitor is an aromatic series compound having a NO.sub.2 group, a SO.sub.3 Na group, and a secondary amino group, representatively, the following compound. In this suspension polymerization, the production of by-produced microfine particles caused by the emulsion polymerization as the secondary polymerization scheme is repressed. ##STR1##
