The polymerization in the system acrylonitrile (AN) - tributyl dimagnesium iodide (TUI) - toluene in the presence of small amounts of 2-vinylpyridine (VP) begins with the formation of short living oligo-blocks of VP which induce the polymerization of

The character of the influence of small amounts of pyridine containing electron donors on the low-temperature polymerization of acrylonitrile initiated by tributyldimagnesium iodide in toluene is determined by the nature of the donor that was selecte

The relative roles of chain propagation and deactivation during polymerization in an acrylonitrile-tributylmagnesium iodide-toluene system were studied. The reaction constants were calculated. It was shown that chemical deactivation of the propagatin

Acrylonitrile (AN) polymerization is more efficiently initiated in toluene by lithium polystyryl (LPS) (up to 55%) than by lithium butyl (∼1%). The styrene-acrylonitrile block copolymers produced had 30–50 mole % of the AN chain units; the molecu

A study was made of the kinetics of polymerization in the systems acrylonitrile-tributyldimagnesium iodide-toluene (I) and methyl acrylate-tributyldimagnesium iodie-toluene (II) in the presence of tetramethylethylenediamine (TMD) and tetraglim (TG).
