Abstract
A polyol polymer having a greater number of hydroxy groups, an aliphatic acid ester of a polyol polymer having a greater number of hydroxy groups, and an aliphatic ether of a polyol polymer having a greater number of hydroxy groups are provided. A polymer obtained by polymerizing a polyol containing meso-erythritol, and an aliphatic acid ester and an aliphatic ether of the polymer are provided.
