WebBulk or Mass Polymerization. In mass or bulk polymerization, the reaction mixture consists mainly of monomers, and in the case of free-radical or ionic polymerization, of vinyl monomers and a soluble initiator. Thus, the polymerization is carried out in undiluted monomers. This type of polymerization is frequently used for step-growth polymers.
