Abstract
A composition comprises a polyglycolide or a polyglycolide copolymer and a filler. The polyglycolide is prepared from glycolide by ring-opening polymerization. The composition may have a tensile modulus greater than 5,800 MPa. The polyglycolide copolymer may have a weight-average molecular weight (Mw) in the range of 10,000-1,000,000 and a ratio of a weight-average molecular weight to a number-average molecular weight (Mw/Mn) in the range of 1.0 to 10.0. The polyglycolide copolymer may have a melt index (MFR) in the range of 0.1 to 1000 g/10 min. Also provided is a process for preparing the composition.
