SYNTHESIS AND CHARACTERIZATION OF EPOXY-ACRYLIC POLYMER ON THE BASIS OF 2-HYDROXY-3-PARA-NONYLPHENOXY-PROPYL ACRYLATE

Poly(2-hydroxy-3-para-nonylphenoxy-propyl acrylate) polymer was synthe sized in solution and in bulk by radical polymerization of 2-hydroxy-3 -para-nonylphenoxy-propyl acrylate monomer. The polymer obtained in so lution is soluble in various organic solvents. It was characterized by IR and H-1-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 viscos ity measured in cyclohexane at 25 degrees C +/- 0.05 is 2.8 x 10(-2) d L/g. The polymer has a non-Newtonian rheological behavior of pronounce d pseudoplastic type. The insoluble polymer has the solubility paramet er 9.2 (cal/mL)(1/2).
