F. Akutsu et al., ANIONIC GRAFT-COPOLYMERIZATION OF METHYL-METHACRYLATE WITH LITHIUM DIISOPROPYLAMIDE-TREATED POLY(METHYL ALPHA-SUBSTITUTED ACRYLATE)S, Macromolecular rapid communications, 17(2), 1996, pp. 101-107
The anionic grafting of methyl methacrylate onto several lithium diiso
propylamide (LDA) - treated polymers of methyl alpha-substituted acryl
ates containing an active methylene or methine group was investigated.
The grafting was carried our using a mole ratio of LDA/acrylate unit
of 0.75 in the feed polymer. The anionic graft copolymerizability of t
hese acrylate polymers largely depends upon the surrounding of the act
ive alpha-hydrogen atom adjoining a carbonyl group or of the carbanion
produced by the LDA treatment in the feed polymer.
