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.

A method of preparing a homopolymer of an .alpha.-trifluoromethylacrylate represented by the general formula (1). comprising the step of keeping the monomer of said .alpha.-trifluoromethylacrylate dissolved in an organic solvent in the presence of an anionic polymerization catalyst which is an alkoxide represented by the general formula (2):
- ##STR3## wherein R represents an alkyl group or a fluorine-containing alkyl group:
- R'OM (2)
- wherein R' represents an alkyl group and M represents an alkali metal.
