苯乙烯与丙烯酸十六醇酯共聚合的竞聚率
|
||
|
我最近在做苯乙烯和丙烯酸高碳酯的共聚合，可是查了很多东西也找不到两者的竞聚率，哪位达人知道啊？赐教一下吧！！！ 多谢了，急等！！！ [ Last edited by machunbao0306 on 2009-2-27 at 13:31 ] |

Journal of Polymer Science Part A-1: Polymer Chemistry， Volume 8, Issue 11 , Pages 3113 - 3121 Reactivity ratios and copolymerization parameters for copolymers incorporating n-octadecyl acrylate and N-n-octadecylacrylamide Article Reactivity ratios and copolymerization parameters for copolymers incorporating n-octadecyl acrylate and N-n-octadecylacrylamide Edmund F. Jordan Jr., Richard Bennett, Andrea C. Shuman, A. N. Wrigley Eastern Utilization Research and Development Division, Agricultural Research Service, U.S. Department of Agriculture, Philadelphia, Pennsylvania 19118 Abstract Monomer reactivity ratios and copolymerization parameters were determined for n-octadecyl acrylate and N-n-octadecylacrylamide with several monomers not previously reported. Values of Q and e for the long-chain acrylate now agreed more closely than before with the average of values for the lower acrylate homologs. The average polarity parameter for N-n-octadecylacrylamide still showed more electron withdrawal from the double bond (e = 0.42) than was expressed by the average literature value (e = -0.10) for N-n-octylacrylamide. Because penultimate effects were absent in this work, the reason for the discrepancy seems to reside in the copolymer analysis. Reactivity ratios for oleyl and octadecyl acrylate with methyl methacrylate were similar. Coefficients for the relation between overall rates of copolymerization and composition were obtained on some systems by curve fitting with a computer. They generally showed a slight minimum. 同时也参考octadecyl acrylate： from Polymer handbook, 4th Edition, Page II/251 Monomer 1 Monomer2 rx ±95% r2 ±95% Styrene, Acrylate, octadecyl 0.777 0.37 Styrene, Acrylate, octadecyl 0.44 0.18 Styrene, Acrylate, octadecyl 0.79 0.31 Styrene, Acrylate, octadecyl 0.44 0.18 可以看出，可以很好的共聚． [ Last edited by walter1977 on 2007-7-26 at 17:23 ] |
