Initiation system activated-PVC/BCl3 [Rudolf Lukáš, Luděk Toman] Summary: A new initiation system is described, allowing bulk polymerizations of isobutylene to be carried out at about-78°C, in the absence of a polar chlorinated solvent. The initiation system consists of two components, the first of which is boron trichloride (BCl3) used as co-initiator, and the other component is a polymer insoluble in the monomer and containing chloroallyl structures or structures with a chlorine atom bound at the tertiary carbon atom in their chains. Bulk polymerizations of isobutylene proceed at the boundary between the solid and the liquid phase for many hours, and the polymeric initiator used is grafted by isobutylene. Dichloromethane raises reactivity of the initiation system.
