Title:
METHOD FOR SYNTHESIZING POLYESTER
Document Type and Number:
Japanese Patent JP2010059421
Kind Code:
A
Abstract:
To provide an enzymatic polymerization method for producing a polyester resin suitable for using in toner production.
In this method, at least two components selected from a group consisting of lactones, lactides, cyclic anhydrides, cyclic carbonates, and their combination, are brought into contact with an enzyme selected from a group consisting of lipase, cutinase, and their combination, and at least two components are polymerized to form a copolyester resin. This process includes a step for recovering the copolyester resin.
