Abstract

The present invention discloses a method of synthesizing an aliphatic polymer having a ketone group in the main chain thereof, in which polyhydric alcohol (for example, glycerin) as a raw material is polymerized in the presence of a catalyst, and a method of preparing a composition containing an aliphatic polymer having a ketone group in the main chain thereof, including such a process.
