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 (Mn(CO)) are reported for the first time.
通过碘转移聚合（ITP）合成了各种基于偏二氟乙烯（VDF）、三氟氯乙烯（CTFE）或CTFE与偏二氯乙烯（VDC）的氟化大分子链转移剂（CTA）。这些大分子CTA参与了进一步的ITP反应，从而合成了具有原创性的基于CTFE的嵌段共聚物，其分子量范围为2500至40000 g/mol，并且具有高热稳定性（在空气中，失重10%时的分解温度约为380°C）。首次报道了由催化量的十羰基二锰（Mn(CO)）在100°C下热引发的CTFE与VDC的ITP以及VDF的ITP。
