dc.description.abstractCopolymers containing N-vinyl-2-pyrrolidone as a common monomer with acrylic acid, 4-methyl styrene and vinyltrichlorosilane of different comonomer compositions were synthesized and characterized. Copolymer composition was determined by elemental analysis, from which monomer reactivity ratios (MRR, r) were estimated using straight line intersection procedures, such as Fineman-Ross and Kelen-Tudos methods, and a nonlinear one, the Reactivity Ratios Error in Variables Model. In this case, the values of MRR are r(VP) = 0.1 and r(AA) = 1.1 (for VP-co-AA), r(VP) = 0.8 and r(4MS) = 14.6 (for VP-co-4MS), and r(VP) = 0.0 and r(VTCS) = 0.3 (for VP-co-VTCS).
dc.description.abstractCopolymers containing blocks of one of the monomer units and another tending to the alternation were obtained, with the product depending on the chemical nature of the comonomers. The different proposed comonomer distributions are analyzed in terms of the obtained MRR values and compared with related systems. The MRR are discussed in terms of monomer structural properties such as electronegativity and electron delocalization.
