Method for producing biodegradable aliphatic polyester and / or copolymer thereof |
| abstract |
PROBLEM TO BE SOLVED: To provide a biodegradable aliphatic polyester and / or a copolymer thereof, in addition to being useful as a medical material or a general-purpose resin substitute. An object of the present invention is to provide a method for producing a biodegradable aliphatic polyester and / or a copolymer thereof using a main raw material in which the total content of organic impurities contained in the raw material is not more than a specific amount. SOLUTION: It is an essential condition to use a raw material in which the total content of organic impurities contained in the raw material is not more than a certain specific amount, and at least a part of the polymerization reaction is performed by using the raw material to perform a solid-state polymerization reaction. Degradable aliphatic polyester and / or Alternatively, a copolymer thereof is produced. |
