PEO-block-MEEP copolymers were synthesized using the controlled cationic polymerization of phosphoramines. The block copolymers synthesized had molar PEO:MEEP rations of 1:0.49, 1:1.2, 1:2.7, and 1:4.9, with the length of the PEO segment held constant at 5400 g/mol. The self-aggregation characteristics of the block copolymers in water were investigated by using UV/vis spectroscopy and dynamic light scattering. A hydrogel of a block copolymer with a molar PEO:MEEP ratio of 1:4.9 was also synthesized, and its temperature dependency was determined.
