CLAIMS

What is claimed is:

A biodegradable polymer, comprising: a component derived from isosorbide at 10 to 50 mol% and a component derived from an aliphatic diol, which has a backbone consisting of 2 to 5 carbon atoms, at 50 to 90 mol% based on total diol components; anda component derived from an aromatic dicarboxylic acid...

DESCRIPTION

[Technical Field]

The present invention relates to a polymer having improved transparency, heat resistance and flexibility by introducing isosorbide into a structure of an aliphatic/aromatic copolyester resin, as a transparent biodegradable polymer.
