Title:
POLYGLYCOLIC ACID RESIN PARTICULATE COMPOSITION FOR BORING, AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2012/121294
Kind Code:
A1
Abstract:
Provided is a polyglycolic acid resin particulate composition that is for boring and that is formed by adding 0.01-15 masses of an antiblocking agent, which preferably is dissolved or broken down in a liquid carrier, for every 100 masses of a polyglycolic acid 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 that is at least the glass transition temperature of the polyglycolic acid resin minus 5°C and a load of 100 gf/cm2 that is loaded for 24 hours is no greater than 1000 gf/cm2, and/or formula F1/F0, which comprises F1 and the vertical breaking stress (F0) of a cylindrical tablet formed from the particulate at the aforementioned forming conditions, is no greater than 0.95. Further provided is a method for producing the particulate composition.
