Title:
BIODEGRADABLE ALIPHATIC POLYESTER RESIN PARTICULATE COMPOSITION AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2012/121296
Kind Code:
A1
Abstract:
Provided is a biodegradable aliphatic polyester resin particulate composition formed by adding an antiblocking agent to a biodegradable aliphatic polyester resin particulate having an average particle size of 0.01-1000 μm. Preferably, the vertical breaking stress (F1) of a cylindrical tablet formed from the particulate composition under the forming conditions of a temperature in the range that is at least the glass transition temperature of the resin minus 5°C and a load of 100 gf/cm2 loaded for 24 hours is no greater than 1000 gf/cm2, and/or the vertical breaking stress (F0) of the cylindrical tablet formed from the particulate under the aforementioned forming conditions is such that F1/F0 ≤ 0.95. Further provided is a method for producing the particulate composition.
