Iodide does the job : Water‐soluble, harmless, cheap, and nonhazardous NaI was used in combination with K 2 S 2 O 8 instead of I 2 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.
