Heat and aging resistant polyglycolide copolymer and composition thereof |
| abstract |
The invention relates novel polyglycolide copolymers comprising a colorant. The copolymers may have a weight-average molecular weight (Mw) in the range of 10, 000-1,000, 000, a ratio of a weight-average molecular weight to a number-average molecular weight (Mw/Mn) in the range of 1.0 to 4.0, and a yellowness index (YI) is the range of 40-90.The copolymers may have a melt index (MFR) in the range of 0.1 to 1000 g/10 min. The copolymers may have a stable yellowness index, good thermal stability and aging resistance. Also provided are a process for preparing the copolymers and a method for reducing yellowness index change rate of a polyglycolide copolymer. |
