Abstract

Abstract: A novel well-defined water-soluble macromonomer based on 2-(dimethylamino) ethyl methacry-late(DMAEMA) was synthesized by using functional initiators such as potassium alcoholate of trimethylol-propane allyl ether via oxyanion-initiated polymerization.GPC and ¹H NMR studies confirmed that themacromonomers had narrow molecular weight distribution and each Poly(DMAEMA) chain contained apolymerizable allyl group.The macromonomers were highly surface active in aqueous media.They havepotential applications in preparation of surface-clean and functional latexes both as effective stabilizers andas co-monomers.

Key words: Oxyanion-initiated polymerization, Y-type macromonomers, 2-(N,N-dimethylamino) ethyl methacrylate (DMAEMA)
