Abstract
The contribution refers to the possibility of using emulsion polymerization of styrene, initiated by a heterogeneous initiator Chydroperoxide of isotactic powdered polypropylene) in the presence of a complex type activator, for the synthesis of block copolymers. Vinylmonomers with various water-solutibility, i.e. methyl methacrylate (MMA), acrylonitrile (AN) and maleic anhydride (MA), were utilized as comonomers of styrene. It was found that at the used conditions, the composition of block copolymers PS-b-P(S/AN) and PS-b-PCS/MA) can be varied by the time of polymerization of the first or second comonomer. The block copolymers were characterized by their molecular weight, and their thermal stability was also investigated.
