MOLECULAR MASS-DISTRIBUTION OF POLYMERS IN BRANCHED RADICAL POLYMERIZATION OF POLYFUNCTIONAL MONOMERS

The change of MMD in the course of radical polymerization of monoallyl derivatives of endomethylenetetrahydrophthalic acid containing (meth) acrylate groups and of triallyl isocyanurate has been studied. The MMD character of polymers synthesized in these processes is the same as for the products of polymerization of diallyl derivatives studied earlier. In spite of the difference in the structure of monomers MMD of polymers up to the gel point have the same polymodal character. Dimensions of branched macromolecules corresponding to the maxima on gel-chromatograms donot depend on the nature of a polyfunctional monomer. Diameters of these molecules are close to 8.18 and 47 nm for most formed branched macromolecules.
