Abstract
There is provided a novel production method of a chlorinated hyperbranched polymer that is optically stable and is capable of derivatizing the chlorinated hyperbranched polymer into various compounds. A production method of a chlorinated hyperbranched polymer for producing a chlorinated hyperbranched polymer of Formula (1): {where X is a chlorine atom; Ris a hydrogen atom or a methyl group; and Ais a phenylene-alkylene group, n is the number of repeating unit structures and is an integer of 2 to 100,000}, comprising the step of substituting a dithiocarbamate group of a hyperbranched polymer of Formula (3): (where R, A, and n are the same as defined in Formula (1); and each of Rand Ris a Calkyl group, a Chydroxyalkyl group, or a Carylalkyl group, or Rand Roptionally form a ring together with a nitrogen atom bonded to Rand R) with a chlorine atom using sulfuryl chloride.
