radical polymerization


Currently, polymers with special properties are widely used in various areas, including medicine and electronic. However, specific of usage of such materials is determined by their structure. In this case, the development of novel polymeric macromolecules with controlled structure and studying of peculiarities their synthesis is an actual task for today. In this paper surface active block/comb-like copolymers were obtained via free radical polymerization by two-step polymerization.

Використання red-ox систем на основі ce4+ для одержання пероксидвмісних полімерів

he heterotelechelic oligomers and block-copolymers with ultimate peroxide, glucose and other functional fragments were synthesized by polymerization, initiated by RedOx system – OH agents and Ce4+ salt in the presence of peroxide chain transfer agent. The structural and colloidal-chemical properties of oligoperoxides were studied.

Selected Radical Azoinitiators in the synthesis of Solvent-Borne Acrylic Pressure-Sensitive Adhesives

Functional azoinitiators: 2,2’-azobis(2-methyl-4-hydroxybutyl propionate) (AIB-BD), 2,2’-azobis[2-methyl-ω-hydroxy-tri(oxyethylene) propionate] [AIB-Tri(OE)] and 2,2’-azobis[2-methyl-ω-hydroxy-oligo(oxyethylene) propionate] [AIB-OOE(400)] were used in radical polymerization of 2-ethylhexyl acrylate, methyl acrylate and acrylic acid in organic solvent ethyl acetate to prepare solvent-borne acrylic pressure-sensitive adhesives (PSA).

Synthesis, polymerization ability, nonlinear optical properties of methacrylic monomers and polymers with benzylidene moiety

New methacrylic monomers, their polymers with benzylidene fragment were synthesized. Structures of all compounds were determined by HNMR, UV- spectroscopies. The third order nonlinear optical properties of oxazolone, thiazolidinone and thiohydantoin containing compounds were investigated in solutions using degenerate four wave mixing (DFWM) method at 532 nm.

Features of Methylmethacrylate Thermopolymerization in the Presence of Intraionic Dues

The polymerization ability of methylmethacrylate (MMA) dymethylforamide (DMF) solutions in the process of their radical thermoinitiated homopolymerization in the presence of intraionic dyes was investigated by a dilatometry method. It was shown that dyes can initiate the polymerization process in the presence of stardart initiator AIBN or without it. This is considerable for colored polymethylmethacrylate (PMMA) obtaining.
