Thus alternating copolymerization is achieved between electronacceptor monomers such as acrylonitrile, methyl acrylate, methyl methacrylate, and methyl vinyl ketone and electron-donor monomers such as propene, isobutylene, vinyl chloride, vinylidene chloride, and vinyl acetate A consideration of the r values in Table 6-2 for these comonomer pairs clearly indicates that the alternating tendency is not high in the absence of the Lewis acid In the presence of the Lewis acid these comonomer pairs become strongly alternating Two mechanisms have been proposed to explain the effect of Lewis acids, both involving initial complexation of the Lewis acid with the electron-acceptor monomer to produce a binary complex with enhanced electron-acceptor properties The binary complex participates in copolymerization either through a cross-propagation mechanism or via interaction with the electron-donor monomer to form a ternary complex that subsequently undergoes homopropagation.

In one case Trajan was advised by Pliny that the money [of an Asiatic city] must lie unemployed because no persons will borrow from the municipality at 12% Trajan replied in favor of offering the money at.

You ve gathered all the needed parts and you ve opened things up. You ve studied the diagram. Now, step by step, you ll complete the transformation. Here s how.

Both mechanisms explain why copolymerization is possible with monomers such as propene or isobutylene, which do not homopolymerize as a result of degradative chain transfer Degradative chain transfer is less competititve with polymerization through the binary or ternary complex Both the cross-propagation and complex mechanisms may be operative in alternating copolymerizations with the relative importance of each depending on the particular reaction system The tendency toward alternation, with or without added Lewis, acid, is temperatureand concentration-dependent Alternation decreases with increasing temperature and decreasing total monomer concentration since the extent of complex formation decreases When the alternation tendency is less than absolute because of high reaction temperature, low monomer concentration, absence of a Lewis acid, or an imbalance in the coordinating abilities of the two monomers, copolymerization proceeds simultaneously by the two mechanisms The quantitative aspects of this situation are considered in Sec 6-5 6-3b-4 Q e Scheme.

Various attempts have been made to place the radical monomer reaction on a quantitative basis in terms of correlating structure with reactivity. Success in this area would give a better understanding of copolymerization behavior and allow the prediction of the monomer reactivity ratios for comonomer pairs that have not yet been copolymerized. A useful correlation is the Q e scheme of Alfrey and Price [1947], who proposed that the rate constant for a radical monomer reaction, for example, for the reaction of M1 radical with M2 monomer, be written as
