Method for producing monoesters and diesters of polytetrahydrofuran and of tetrahydrofuran copolymers |
| abstract |
The present invention relates to a process for producing monoesters or diesters of polytetrahydrofuran or tetrahydrofuran copolymers by polymerization of tetrahydrofuran in the presence of one or more telogens and / or comonomers on acidic catalysts. According to the invention the polymerization reactor is a monoester or diester of polytetrahydrofuran, polytetrahydrofuran and / or THF copolymer, tetrahydrofuran, any comonomer and one or more carboxylic acids and / or one or more carboxyl It is started using a mixture consisting of acid anhydrides. |
