WebPolymerization is initiated by oxidation of the monomer into radical cations, which in turn combine to form dimers, trimers, oligomers, and finally polymers in the bulk of the solution, which precipitate as insoluble polymer particles. While the bulk polymerization is taking place, some polymer deposition occurs directly on the substrate. WebKraton polymers are styrenic block copolymer (SBC) consisting of polystyrene blocks and rubber blocks. The rubber blocks consist of polybutadiene, polyisoprene, or their hydrogenated equivalents. The tri-block with polystyrene blocks at both extremities linked together by a rubber block is the most important polymer structure observed in SBC.
