| 摘要 |
An aqueous dispersion of a biodegradable polyester, which comprises a copolymer of 3-hydroxybutylate and 3-hydroxyhexanoate having a weight averag e molecular weight of 50,000 to 3,000,000 and a flexural modulus of 100 to 150 0 MPa, wherein the copolymer has an average particle diameter of 0.1 to 50 .mu .m in the aqueous dispersion. The aqueous dispersion of a biodegradable polyest er is excellent in film forming characteristics and can provide a resin coating film which is soft, exhibits good elongation and is proof to bending, when i t is applied to a coating material, an adhesive agent, fiber texturing, sheet or film processing, paper conversion or the like.
