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 of ethylene and vinyl acetate via reversible addition–fragmentation chain transfer polymerization. Benefiting from the good chain growth control of polyethylene (PE), poly(vinyl acetate) (PVAc), and poly(ethylene‐ co ‐vinyl acetate) (EVA) achieved with this CTA, linear diblock copolymers of the type EVA‐ b ‐PE, EVA‐ b ‐EVA, and PVAc‐ b ‐EVA are successfully synthesized. A three‐arm EVA star is additionally obtained starting from a trifunctional dithiocarbamate CTA.
