Stereoregulation during the oligomerization of TRITYL METHACRYLATE (cas 19302-93-3)

Add time:07/31/2019    Source:sciencedirect.com

For the first time, uniform optically active oligomers of methyl methacrylate with degrees of polymerization (DP) = 1, 2, 3, and 4 were obtained by the anionic polymerization of trityl methacrylate using 1,1-diphenylhexyl lithium/(−)sparteine, followed by the substitution of trityl for methyl, and subsequent g.p.c. separation. The mechanism for the formation of optically active poly(trityl methacrylate) is discussed in this paper.
