Patent ID: 8623944

Claim:
A method for making a biodegradable product, consisting of the following steps: a. providing (i) a bio-molecule selected from the group consisting of vegetable gelatin, animal protein, agar, chitosen, hyaluronic acid and a mixture thereof, and (ii) a precursor monomer or oligomer of a biodegradable polyester; b. mixing 100 parts by weight of the bio-molecule with 0.1 to 200 parts by weight of the precursor monomer or oligomer of a biodegradable polyester to obtain a first mixture and thermally-treating the first mixture at 50° C. to 160° C. to obtain a plasticizer; and c. mixing the plasticizer with a biodegradable material at 160° C. to 280° C. to obtain a second mixture and thermally-treating the second mixture at 160° C. to 280° C. to obtain the biodegradable product; wherein the biodegradable material comprises a biodegradable polymer having a monomer or oligomer that is the same as the precursor monomer or oligomer of a biodegradable polyester of step a.
