Abstract
AbstractRadical copolymerization of maleic anhydride (MA) with a number of electron‐donor monomers has been investigated. Charge transfer complexes (CTC) of MA with vinyltriethoxysilane (VTES), vinylcyclohexylcetone (VCHC), and styrene (St) have been fixed. On the basis of NMR and ultraviolet spectroscopy data, the equilibria constants of complexation (K)1 and extinction coefficient (ε) for various pairs of donor‐accepting monomers have been determined. The terpolymerization has been carried out involving the mentioned monomeric CTC (complexomer). Copolymerization constants r2 and r2), specific activity (Q), and polarity (e) factors for monomer and complexomer pairs, constituting the systems: MA‐St‐VTES, MA‐St‐NCH, and MA‐St‐VCHC have been determined. Some regularities of terpolymerization with MA complexomers present have been revealed. It has been shown that the three‐component system polymerizes at the stage two‐component polymerization of either complexomer MA‐St with VTES (or NCH) or two complexomers MA‐St with MA‐VTES (or MA‐NCH).
