Abstract

An amino alcohol was synthesized on the basis of piperidine and epichlorohydrin. The esterification reaction of methacrylic acids with the obtained amino alcohol was studied. In order to identify optimal synthesis conditions, the influence of temperature, reaction duration and ratio of reactive reagents was investigated. The processes of obtaining unsaturated esters by esterification reactions with 1-chlorine-3-piperidine-2-propanol and acrylic-, methacrylic acids have been studied. The effect of monomer concentration on the rate of polymerization reaction and the yield of polymer formation was studied . The radical polymerization of a new monomer with a piperidine cycle in the presence of a nitrogen-containing initiator in the environment of organic solvents was investigated. The influence on the polymerization process of such factors as the nature of the solvent, temperature, monomer and initiator concentration is studied. The main kinetic and energy parameters of the homopolymerization reaction are determined. The found values of the reaction orders for the monomer and initiators are 1.5 and 0.56, respectively, and the process activation energy is 59.8 kJ / mol. A synthesized crosslinked high molecular compound based on 1-chloro-3-piperidino-2-propylmetacrylate. The physicochemical properties of the obtained compound were studied, the rate of swelling in water and other media, resistance to degradation, and mechanical strength were determined . 1-chlorine-3-piperidine-2-propyl methacrylate (XPPMA) ing structure IQ , PMR-spectroscopy, chromatic-mass spectrometry methods were approved. The average characteristic viscosity of poly -1-chlorine-3-piperidine-2-propyl- methacrylate was determined by viscometric method .
