Use of Sodium Iodide as the Precursor to the Control Agent in Ab Initio Emulsion Polymerization

Abstract

Iodide does the job: Water-soluble, harmless, cheap, and nonhazardous NaI was used in combination with K2S2O8 instead of I2 itself to produce an uncolored living poly(butyl acrylate) latex of controlled molecular weight by a single-step polymerization process (see scheme for one polymerization pathway). Reactivation of the polymer then yielded a block-copolymer latex. BuA=butyl acrylate.
