Dispersion polymerization of n ‐butyl acrylate has been performed in a mixture of ethanol and water in the presence of poly( N ‐acryloylmorpholine) (polyNAM). These hydrophilic polymer chains are synthesized by the RAFT process and thus incorporate well‐defined chain ends. The dithioester ω ‐end group is used as an efficient chain transfer agent under dispersion polymerization conditions to produce hairy poly( n ‐butyl acrylate) latex particles. Moreover, pre‐functionalization of the polyNAM chains on the α ‐end by a carbohydrate derivative is also achieved to obtain directly functionalized particles according to the same strategy.
