Synthesis and kinetic regularities of copolymers based on styrene and nitrogen-containing methacrylic monomers

Abstract

In this study, the synthesis and kinetic regularities of the radical copolymerization of N-morpholin-3-chloropropylacrylate (MXIPMA) with styrene were investigated. The copolymerization was carried out in bulk at 70 °C in the presence of azobisisobutyronitrile (AIBN) as an initiator. The effects of monomer ratio, reaction time, and temperature on the conversion degree and copolymer composition were analyzed. The obtained results demonstrated that the introduction of a morpholine-containing nitrogen fragment into the methacrylate structure significantly affects the copolymerization rate and thermal stability of the resulting copolymers. Due to their high polarity and solubility, the synthesized copolymers show potential for use as lubricant modifiers.
