Synthesis and Characterization of Epoxy-Acrylic Polymer on the Basis of 2-Hydroxy-3-para-nonylphenoxy-propyl Acrylate

Poly(2-hydroxy-3-para-nonylphenoxy-propylacrylate) polymer was synthesized in solution and in bulk by radical polymerization of 2-hydroxy-3-para-nonylphenoxy-propylacrylate monomer. The polymer obtained in solution is soluble in various organic solvents. It was characterized by IR and 1 H-NMR spectroscopy, cryoscopy, and viscometric behavior. The polymer synthesized in bulk is insoluble. It was characterized by IR spectroscopy and by solubility parameter. The number-average molecular weight of the soluble polymer is around 3100 and the intrinsic viscosity measured in cyclohexane at 25°C ± 0.05 is 2.8 × 10 −2 dL/g. The polymer has a non-Newtonian Theological behavior of pronounced pseudoplastic type. The insoluble polymer has the solubility parameter 9.2 (cal/mL) 1/2 .
