The impact of the vinyl monomers nature, concentration, and temperature on the kinetics of dispersion polymerization in the presence of polyvinylpyrrolidone was studied. The optimal technological parameters of the copolymer synthesis process are determined. It is defined that the properties of dispersion polymerization depend on the process conditions.
The method for obtaining coumarone-indene resins with methacrylic fragments (CIRM) was developed with the addition of methyl methacrylate, using a light fraction of coal tar and its fraction boiling within 423–463 К. CIRM was obtained via radical cooligomerization using 2,2'-azobis (2-methyl-propionitrile) as the initiator. The effect of the initiator amount, temperature and reaction time on the yield, softening temperature and molecular weight of CIRM has been established. The structure of the synthesized CIRM has been confirmed by IR and NMR spectroscopy.
