Poly(ethylene oxide) (PEO) with dithiocarbamate chain ends (PEO-SC(=S)-N(CH3 )Ph and PEO-SC(=S)-NPh2 , named PEO-1 PEO-2, respectively) were used as macromolecular chain-transfer agents (macro-CTAs) to mediate the reversible addition-fragmentation transfer (RAFT) polymerization of ethylene in dimethyl carbonate (DMC) under relatively mild conditions (80 °C, 80 bar). While only a slow consumption was observed, rapid PEO-2 led clean extension formation polyethylene (PE) segment. Upon...
Abstract Controlled radical polymerization of ethylene using different commercially available, cheap, and non‐toxic iodo alkyls is performed by iodine transfer (ITP) under mild conditions (≤100 °C ≤200 bar). The formed well‐defined end‐capped polyethylene (PE−I) species very stable upon storage. Narrow molar‐mass distributions (dispersities around 1.6) were obtained up to number average molar masses 7300 g mol −1 . copolymerization ITP (ITcoP) with vinyl acetate allowed form a broad range...

Abstract A dithiocarbamate chain transfer agent (CTA) based on Z‐group substituted with a diphenyl amine (–NPh 2 ) moiety is selected for the synthesis of statistical and diblock copolymers ethylene vinyl acetate via reversible addition–fragmentation polymerization. Benefiting from good growth control polyethylene (PE), poly(vinyl acetate) (PVAc), poly(ethylene‐ co ‐vinyl (EVA) achieved this CTA, linear type EVA‐ b ‐PE, ‐EVA, PVAc‐ ‐EVA are successfully synthesized. three‐arm EVA star...
Two scalable polymerisation methods are used in combination for the synthesis of ethylene and methacrylate block copolymers. ω-Unsaturated methacrylic oligomers (MMA
Iodine transfer (co)polymerization (ITP) was employed to form polyethylene (PE) and poly(ethylene- co -vinyl acetate) (EVA) stars.
Difunctional iodo chain transfer agents (CTAs) were successfully employed in the iodine polymerization (ITP) of ethylene and its copolymerization with vinyl acetate to synthesize telechelic (co)polymers triblock copolymers.

We report the synthesis of PE and poly(ethylene-co-vinyl acetate) (EVA) bearing a low content in-chain thioester functions introduced via co- or terpolymerization approach involving ethylene (E), vinyl acetate (VAc), ε-thionocaprolactone (TCL). To achieve homogeneous incorporation along chains resulting from ring opening TCL, semibatch process with an adjusted feed TCL was employed. Characterizations polymers were conducted by combination size exclusion chromatography (SEC) nuclear magnetic...
