Abstract
A method for carrying out a mass polymerization of monomers and/or pre-polymers, which are at least partially soluble in their polymers, in particular methyl methacrylate (MMA) is provided. The method involves the addition of at least one monomer or pre-polymer in a reactor. Mass polymerization for amorphous polymers is carried out without solvents below the glass transition temperature and for crystalline polymers below the melting point, achieving a high degree of conversion of the monomers.
