Abstract:
Various fluorinated macro-chain transfer agents (CTAs) based on vinylidene fluoride (VDF), chlorotrifluoroethylene (CTFE), or CTFE and vinylidene chloride (VDC), were synthesized by iodine transfer polymerization (ITP). These macro-CTAs were involved in a further ITP reaction that led to the synthesis of original CTFE-based block copolymers exhibiting molecular weight ranging from 2500 to 40000 g/mol and endowed with high thermal stabilities (decomposition temperature at 10% weight loss of ca. 380 °C, under air). ITP of CTFE and VDC as well as ITP of VDF thermally initiated at 100 °C by a catalytic amount of dimanganese decacarbonyl (Mn2(CO)10) are reported for the first time.

Consider the bromination of cyclopentene. Molecular bromine is polarized in the proximity of the π electrons of cyclopentene. An electrophilic bromine atom adds across the double bond, forming a cyclic bromonium ion intermediate.
