Abstract
The radical copolymerization of allyl alkyl ethers with vinyl acetate has been studied in the feed range from 10 to 90 mol% allyl alkyl ethers. The following values were obtained by the Kelen-Tüdös method for the reactivity ratios: allyl ethyl ether (M1)-vinyl acetate (M2), r1=0.041±0.002, r2=1.56±0.08; allyl propyl ether (M1)-vinyl acetate (M2), r2=0.036±0.002, r2=1.39±0.07; allyl butyl ether (M1)-vinyl acetate (M2), r1=0.047±0.003, r2=1.39±0.07; allyl isopropyl ether (M1)-vinyl acetate (M2), r1=0.028±0.002, r2=1.56±0.08; allyl t-butyl ether ether(M1)-vinyl acetate (M2), r1=0.0057±0.0003, r2=1.51±0.08; The Q-e parameters were calculated from the allyl ether(M1)-vinyl acetate (M2) reactivity ratios. The e parameters of allylic monomers have been found to be nicely correlated with parameters such as Taft’s σ* constants of the alkyl group for allyl alkyl ether, 13C NMR chemical shift values of the γ carbon in the allylic monomers, and further, frR for the γ carbon of allyl group in the allylic monomers.
