ABSTRACT:
An improved polymerization process wherein starting material such as monomer, a mixture of monomers, a partially polymerized product, or a mixture of fully polymerized product and monomer or monomer mixture is reacted with an initiator such as an organic peroxide, hydroperoxide or perester and a quaternary ammonium salt under polymerization conditions wherein polymerization or further polymerization of the starting material is initiated. The initiator and quaternary ammonium salt are miscible with the polymerization mixture in the absence of solvent. An improved polymerization process is also provided wherein a crosslinked polymer structure is formed from an unsaturated polymer in a polymerizable monomer.
