Did you know?
Polyglycolide or poly(glycolic acid) (PGA), also spelled as polyglycolic acid, is a biodegradable, thermoplastic polymer and the simplest linear, aliphatic polyester. It can be prepared starting from glycolic acid by means of polycondensation or ring-opening polymerization. PGA has been known since 1954 as a … See more Polyglycolide has a glass transition temperature between 35 and 40 °C and its melting point is reported to be in the range of 225 to 230 °C. PGA also exhibits an elevated degree of crystallinity, around 45–55%, thus … See more Polyglycolide is characterized by hydrolytic instability owing to the presence of the ester linkage in its backbone. The degradation process is erosive and appears to take place in two steps during which the polymer is converted back to its monomer glycolic … See more Polyglycolide can be obtained through several different processes starting with different materials: 1. polycondensation of glycolic acid; 2. ring-opening polymerization of glycolide; 3. solid-state polycondensation of halogenoacetates See more While known since 1954, PGA had found little use because of its sensitivity to hydrolysis when compared with other synthetic polymers. However, in 1962 this polymer was used to develop the first synthetic absorbable suture which was marketed under the See more WebIn the case of hexafiuoroacetone sesquihydrate solutions of polyglycolic acid, it has been found that solutions containing from about 0.01% to about 40% poly glycolic acid can be …
