Patent ID: 11932725
Assignee: ECOVANCE CO. LTD.
Field: Macromolecular chemistry, polymers (Chemistry)
Classification: CPC C  Y | IPC C

Claim 1:
2. The biodegradable polyester resin of claim 1, wherein the biodegradable polyester resin has a molding index (FI) of 25 to 53 represented by the following Equation 2:

Molding index (FI)=TS/FC  [Equation 2]

in Equation 2, TS and FC are values, exclusive of units, measured for a specimen of a biodegradable polyester sheet prepared from the biodegradable polyester resin,
TS is the tear strength (N/cm) measured using a universal testing machine (UTM) for a specimen that has been made according to KSM 6518-B, and
FC is the coefficient of static friction measured by contacting one surface of the specimen with stainless steel (SUS) according to ASTM D1894.
