Abstract
Various fluorinated macro-chain transfer agents(CTAs) based on vinylidene fluoride (VDF), chlorotrifluoro-ethylene (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 to40000 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 ofdimanganese decacarbonyl (Mn2(CO)10) are reported for thefirst time.
