Title: Method for producing ultrahigh-molecular weight polyester
Inventor: CHIZUKA TAKESHI
IPC: C08G63/80
Filed: 2003-03-19
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method for producing an ultrahigh-molecular weight polyester having excellent handleability during molding processing after polymerization and ≥2.0 intrinsic viscosity.  <P>SOLUTION: The method for producing the ultrahigh-molecular weight polyester is carried out as follows. When the polyester is polymerized by using an aromatic dicarboxylic acid and a glycol as starting raw materials, the aromatic dicarboxylic acid and the glycol are initially prepolymerized to provide a polyester. The prepolymerized polyester is heat-treated in a solvent undissolving the polyester and solid phase polymerization is then carried out. Thereby, the linear polyester having ≥2.0 intrinsic viscosity is obtained.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
