A method of manufacturing the same, and the use of the low melt viscosity polyglycolic acid and low melt viscosity polyglycolic acid

摘要

Melt viscosity measured at a shear rate of 122sec ^-1 higher temperature and 10 ℃ than the melting point is 100Pa · s or less, 3% heat weight loss temperature is 280 ℃ or more, the moisture content is 500ppm or less, and, at a temperature of 20 ± 15 ℃ low melt viscosity polyglycolic acid and a process for making a low melt viscosity polyglycolic acid and a heat treatment step and the moisture absorption step polyglycolic acid having high melt viscosity in the solid state in the solid state.
