    Reversible addition-fragmentation chain transfer (RAFT) polymerization of lauryl methacrylate (LMA) in the presence of S-methoxycarbonyl phenylmethyl dithiobenzoate (MCPDB) as a RAFT chain transfer agent (CTA) and subsequent RAFT polymerization of poly(ethylene oxide) monomethyl ether methacrylate (PEO5MEMA or PEO45MEMA) was done with the aim to prepare amphiphilic diblock copolymer brushes of controlled structure. The molecular weight of PLMA and PLMA-b-PPEO5MEMA copolymers was evaluated by several methods Several diblock copolymers PLMAb- PPEO5MEMA with various lengths of the blocks and a high molecular weight (Mn up to 300 000) were prepared and characterized. RAFT polymerization of PEO45MEMA from PLMA as a macro-CTA failed.
