ABSTRACT:
What is disclosed is a method for the partial polymerization of at least one vinyl monomer to form a mixture of said monomer with a polymer thereof, which comprises initiating polymerization of said monomer with a percarbonic acid ester and inhibiting further polymerization when the desired mixture is formed by addition thereto of a thioether, an organic disulfide, or a mercaptan, as are the partially-polymerized mixtures so produced, and their use for forming an organic glass by further polymerization thereof.
