The reactions of co-polymerization of perfluoroalkyl(meth)acrylates (niF(M)A)) with MMA, styrene and dimethylvinylethynilcarbynol (DVEC) in mass, in benzoyl peroxid (BPO) presence are studied using GLC.NMR-H' spectroscopy high resolution. UV-and IR-spectroscopy and dilatometry. Constants of copolymerization rij and rji, distribution of homo- and helerodiades in macromolecular chain and copolymerization speed are determined using data of composition of co-polymers. Quantum chemical parameters of vinyl groups of perfluoroa!kyl(meth)acrylates in radical co-polymerization with the above-mentioned monomers on the basis of received results is determined. The optical, thermomechanical properties and thermo-oxygenational stability of the obtained co-polymers are studied. The dependence of these properties on structure of niF(M)A and their molar ratio in the reaction mixture and conditions of reactions are established. |
