Copolymers of 2-hydroxy-3-(N-methyl-N-phenylamino)propyl methacrylate with methyl methacrylate and their microstructure

A precursor for the production of azo chromophores, viz. 2-hydroxy-3-(N-methyl-N-phenylamino)propyl methacrylate, was prepared and characterized. Its copolymerization with methyl methacrylate was carried out and the copolymerization constants were determined: for 2-hydroxy-3-(N-methyl-N-phenylamino) propyl methacrylate, r₁ = 0.50; for methyl methacrylate, r₂ = 0.93. The average block lengths of monomers of the same type depending on the composition of the copolymer were estimated.
