SYNTHESIS AND PROPERTIES OF REGULAR COPOLYMERS .2. SPECTROSCOPIC ANALYSIS OF REGULAR COPOLYMERS OF VINYL COMPOUNDS WITH ALIPHATIC DIHALIDES

I.r. and n.m.r. spectra of polymers prepared by reacting vinyl. monomer with alkali metal in the presence of aliphatic dihalides are discussed and indicate that the materials may be described in general as regular copolymers of repeat unit [MRM] where M is monomer and R is the ligand of the dihalide. The spectra of those polymers prepared with vicinal dihalides, however, confirm that head-head homopolymer is prepared by an elimination reaction. The chemical shifts of a number of such polymers are listed and assigned, and the correlation of these assignments with the polymeric structures is discussed. © 1969.
