In 2019,Macromolecular Chemistry and Physics included an article by Cao, Yakun; Kumar, Rajesh; Tsarevsky, Nicolay V.. Product Details of 88-67-5. The article was titled 《Employing Heterocyclic Hypervalent Iodine Compounds with I-Cl Bonds as Initiators and Chain Transfer Agents in the Synthesis of Branched Polymers》. The information in the text is summarized as follows:
Heterocyclic hypervalent (HV) I(III) compounds with I-Cl bonds and various substituents at the N atom are synthesized and are very efficient chain transfer agents in the polymerization of styrene with transfer coefficients exceeding that of CCl4 by 2-3 orders of magnitude, depending on the structure. The chain transfer rate coefficients are also determined Due to the presence of thermally labile HV bonds, the compounds degrade homolytically upon heating and can initiate radical polymerization For instance, 1-chloro-2-hexyl-1,2-benziodazol-3(2H)-one, is used in the polymerization of styrene, which yields low mol. weight polymers with alkyl chloride groups at the α- (initiation) and the ω-chain ends (transfer). Chain-end functionalization reactions with azide and chain extension under low-catalyst-concentration atom transfer radical polymerization (ATRP) conditions of the prepared telechelic polymers are carried out. The same initiator/chain transfer agent is successfully employed in the synthesis of highly branched polymers with multiple alkyl chloride-type chain ends when added to mixtures of styrene and 1,4-divinylbenzene containing 10-80 mol% of the divinyl crosslinker, or even pure crosslinker. In all cases, soluble hyperbranched polymers are obtained up to moderate monomer conversions. The effects of crosslinker and HV I(III) compound concentrations on the polymerization outcome are studied systematically. The experimental part of the paper was very detailed, including the reaction process of 2-Iodobenzoic acid(cas: 88-67-5Product Details of 88-67-5)
2-Iodobenzoic acid(cas: 88-67-5) belongs to organic iodides. The carbon-iodine bond is weaker than other carbon-halogen bonds due to the poor electronegative nature of the iodine atom. In general, organic iodides are light-sensitive and turn yellow during storage, owing to the formation of iodine.Product Details of 88-67-5
