POLYMERIZATION AND CO-POLYMERIZATION PROCESS OF BUTYLENE AND VINYL AROMATIC MONOMERS

A polymerisation and co-polymerisation process of butylene and vinyl aromatic monomers leading to production of polybutylene and polyvinyl aromatic polymers, grafted and telechelic copolymers and polybutylene oils, which is performed at +20 to - 120 degrees C in the presence of an initiation system, whose first component is a polymer, oligomer and/or alkylhalogenide with number of carbons (R) 4 containing in the chain at least one bond of tertiary carbon-halogen and second compound is stannic chloride, or its mixture with ferric chloride. The molar ratio of stannic chloride to the monomer is 50 to 1.10, causing the occurrence of a chemically linked initiator compound corresponding to the polymer, oligomer or alkylhalogenide used, possibly in an environment of polar halogen solvents or their mixture with non-polar or aromatic solvents.
