| Résumé : |
Novel dihydroxy functional 3-arm star polymers were synthesized using a combination of atom transfer radical polymerization, ring opening polymerization, and click chemistry. The diols were characterized using gel permeation chromatography, Fourier transform infrared spectroscopy, and 1H NMR spectroscopy. The diols were incorporated into polyurethane coatings, which were characterized using differential scanning calorimetry, thermogravimetric analysis, pendulum hardness, water contact angle, and methyl ethyl ketone double rubs. The coatings showed an increase in the water contact angle values as the percentage of the polystyrene-based diol was increased. Similarly, the coatings with the poly(tert-butyl acrylate)-based diols showed a decrease in the glass transition temperature values with an increase in the diol content. It is expected that the use of controlled radical polymerization would allow for the synthesis of novel tailor-made functional polymers to achieve tunable coatings properties. |
