ABSTRACT:
A methanol-insoluble homopolymer of an .alpha.-trifluoromethylacrylate, which has either an alkyl group or a fluorine-containing alkyl group in the ester radical, is formed at good yields in an organic aprotic solvent by using an alkali metal alkoxide, e.g. lithium t-butoxide, as anionic polymerization catalyst.
