| 中文摘要 | soluble ndcl3 center dot 3ehoh (2-ethyl hexanol) in hexane combined with alet3 is highly active for isoprene polymerization in hexane. the ndcl3 center dot 3ehoh/alet3 has higher activity than the typical binary catalyst ndcl3 center dot 3(i)proh (isopropanol)/alet3 and ternary catalyst ndv3 (neodymium versatate)/alet2cl/al(i-bu)(2)h. the molecular weight of polyisoprenes can be controlled by variation of [nd], [al]/[nd] ratio and polymerization temperature and time. the ndcl3 center dot 3ehoh/alet3 catalyst polymerized isoprene to afford products featuring high cis-1,4 stereospecificity (ca. 96%), high molecular weight (ca. 10(5)) and relatively narr ow molecular weight distributions (m-w/m-n = 2.0-2.8) simultaneously. more importantly, some living polymerization characteristics were demonstrated: (a) absence of chain termination; (b) linear correlation between m-n and polymer yield; (c) increment of molecular weight in the 'seeding' polymerization. though some deviation from the typical living polymerization such as molecular weight distribution is not narrow enough and the line of m-n and polymer yield does not extrapolate to zero, controlled polymerization with the current catalyst can still be concluded. |
