06224 IUPAC Gold Book - syndiotactic macromolecule 10.1351/goldbook.S06224 S06224 current 1 A tactic macromolecule, essentially comprising alternating enantiomeric configurational base units, which have chiral or prochiral atoms in the main chain in a unique arrangement with respect to their adjacent constitutional units. In a syndiotactic macromolecule, the configurational repeating unit consists of two configurational base units that are enantiomeric. A syndiotactic macromolecule consists of racemo diads. chiral https://goldbook.iupac.org//terms/view/C01057 configurational base units https://goldbook.iupac.org//terms/view/C01250 constitutional units https://goldbook.iupac.org//terms/view/C01288 main chain https://goldbook.iupac.org//terms/view/M03694 racemo diads https://goldbook.iupac.org//terms/view/R05031 tactic macromolecule https://goldbook.iupac.org//terms/view/T06245 PAC, 1996, 68, 2287.
