Specific Features of Thermochemically Initiated Radical Copolymerization of Mixtures of Methacrylic Monomers in the Presence of Dissolved Polyvinyl Butyral

详细

Thermochemically initiated radical copolymerization of a mixture of di(1-methacryloxy-3-chloropropoxy-2-)methylphosphonate (FOM-II) and 2-hydroxypropyl methacrylate in the bulk in the presence of 1–10 wt % dissolved polyvinyl butyral was studied. The process is characterized by two and more self-acceleration periods. This is associated with specific features of FOM-II polymerization transformations and with the presence of polyvinyl butyral macromolecules capable of association with methacrylic monomer molecules in the polymerizing system.
