Notes:
The radical polymerization of methylmethacrylate (MMA) in the presence of a hydroxyl-functional chain transfer agent (2-mercaptoethanol) followed by reaction with 2-isocyanatoethylmethacrylate (IEM) yielded macromonomers with molecular weights in the range of 6,5 · 103 to 23,2 · 103. Homopolymerization of the latter gave highly compact molecules which showed a solution behaviour like linear PMMA of MW = 55 000 but having a real molecular weight of 1,02 · 106. Copolymerization with methacrylic acid delivered comb-like amphiphilic graftcopolymers with a yield of 89 %.
