Patent ID: 8304500

Claim:
A particulate polyglycolic acid resin blend comprising: a first particulate polyglycolic acid resin and a second particulate polyglycolic acid resin each in a form of pellets and having a moisture content of at most 110 ppm, wherein: the first and second particulate polyglycolic acid resins have a first measured melt-viscosity and a second measured melt viscosity, respectively, as measured at 270° C. and a shear rate of 121 sec −1 , thus providing a ratio therebetween of at least 1.05 and at most 3, the first and the second particulate polyglycolic acid resins are identical to each other in chemical composition, at least one of the first particulate polyglycolic acid resin and the second particulate polyglycolic acid resin comprises a thermal stabilizer, and the first particulate polyglycolic acid resin and the second particulate polyglycolic acid resin have particle sizes of 1-4 mm.
