4. Anionic polymerization of protected N-isopropylacrylamide using trialkylaluminum offered highly isotactic
poly (N-isopropylacrylamide), a substituted polyacrylamide; see: Kitayama T, Shibuya W, Katsukawa
K (2002) Polym J 34:405. However, synthesizing unsubstituted polyacrylamide requires polymerizing
a monomer such as N,O-Bis(trimethylsilyl)acrylamide. This monomer was not possible to polymerize
using n-butyl lithium or 1,1-diphenyl ethyl lithium initiators. Dasgupta A, Chakrapani S, Sivaram
S unpublished results. Instability of silyl protection towards anionic initiators is also observed
for silyl enol ethers; see: Hirao A, Kato K, Nakahama S (1992) Macromolecules 25:535–540
