A lactone compound represented by following General Formula (1), such as µ-caprolactone, is reacted in the presence of a powdered activated carbon where necessary with an initiator such as a polyhydric alcohol, an aliphatic alcohol, or an aliphatic carboxylic acid to thereby yield, for example, a polylactone, a polylactone alkyl ether, or a polylactone alkyl ester.
Wherein R 1 is an alkylene group having two to eighteen carbon atoms which may be substituted with one or more alkyl groups each having one or more carbon atoms. Accordingly, a target compound can be produced in a high yield with high quality, from which the catalyst can be easily removed.
