Synthesis of Amphiphilic Statistical Copolymers Bearing Methoxyethyl and Phosphorylcholine Groups and Their Self-Association Behavior in Water
Biocompatible amphiphilic statistical copolymers P(MEA/MPC<i><sub>m</sub></i>) composed of 2-methoxyethyl acrylate (MEA) and 2-methacryloyloxyethyl phosphorylcholine (MPC) were prepared with three different mol% of the hydrophilic unit MPC (<i>m</i> = 6, 12 and 46...

description | Biocompatible amphiphilic statistical copolymers P(MEA/MPC<i><sub>m</sub></i>) composed of 2-methoxyethyl acrylate (MEA) and 2-methacryloyloxyethyl phosphorylcholine (MPC) were prepared with three different mol% of the hydrophilic unit MPC (<i>m</i> = 6, 12 and 46 mol%). The monomer reactivity ratios of MEA (<i>r</i><sub>MEA</sub>) and MPC (<i>r</i><sub>MPC</sub>) were 0.53 and 2.21, respectively. The <i>r</i><sub>MEA</sub> × <i>r</i><sub>MPC</sub> value of 1.17 demonstrated that statistical copolymerization was successful. P(MEA/MPC<sub>12</sub>) and P(MEA/MPC<sub>46</sub>) copolymers did not undergo aggregation in water, whereas the P(MEA/MPC<sub>6</sub>) copolymer formed micelles in water with a hydrodynamic radius (<i>R</i><sub>h</sub>) of 96.9 nm and a critical aggregation concentration, which was determined using pyrene fluorescence, at 0.0082 g/L. The restricted motion of the protons in the hydrophobic MEA units in the micelles’ cores provided additional evidence of self-association in P(MEA/MPC<sub>6</sub>). |
