The influence of the solubility parameter on the regularities of obtaining polymer dispersions based on copolymers of 2-hydroxyethyl methacrylate and glycidyl methacrylate are investigated. A method of nucleating polymerization for obtaining micron-sized monodispersed spherical materials is proposed. The influence of the nature and amount of solvent on the dispersion characteristics of the polymer particles has been established.
Coumarone-indene resins with epoxy groups (CIRE) have been obtained using light fraction of coal tar or fraction with the distillation range of 423–463 K based on it. Styrene and glycidyl methacrylate were used as modifiers. CIRE were synthesized via radical cooligomerization using monoperoxide derivative of dioxyphenylpropane diglycidyl ether (PO) as an initiator. Thermal stability of PO has been studied. The effect of initiator amount, reaction temperature and time on the yield and softening temperature of CIRE has been determined.
Coumarone-indene resins (CIR) with carboxy groups were synthesized via cooligomerization of unsaturated compounds presented in light fraction of coal tar and its fraction boiling out within 423–463 K with the addition of such industrial monomers as styrene, maleic anhydride, glycidyl methacrylate and methacrylic acid. 2,2`-Azobis(2-methylpropionitrile) in the form of 0.2 M solution in toluene was used as an initiator. The effect of monomers nature, initiator amount, temperature and reaction time on the yield and characteristics of resulted CIR has been determined.
