A dithiocarbamate chain transfer agent (CTA) based on Z-group substituted with a diphenyl amine (-NPh 2) moiety was selected for the synthesis of statistical and diblock copolymers of ethylene (E) and vinyl acetate (VAc) via reversible addition-fragmentation chain transfer polymerization. Benefiting from the good control chain growth of poly(ethylene) (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 were successfully synthesized. A three-arm EVA star was additionally obtained starting from a trifunctional dithiocarbamate CTA.
