ABSTRACT: A poly(ethylene
glycol) (PEG) based macroinitiator (MI) with terminal chloride atom at both
ends was prepared by the reaction of PEG-400 with chloroacetyl chloride and
used for the cationic polymerization of dodecyl vinyl ether (DVE) yielding ABA
type block copolymer. The block copolymer was then used as the surfactant for
the emulsion polymerization of vinyl acetate and styrene in the presence of
potassium persulfate as an initiator. The effects of new polymeric emulsifier
on the physicochemical properties of obtained latexes were investigated depending
on surfactant percentage in homopolymerizations.
