| titleOfInvention | A kind of synthetic method of hyperbranched poly tetrahydrofuran |
| abstract | The invention discloses a kind of methods that hyperbranched poly tetrahydrofuran is catalyzed and synthesized with rare earth catalyst, it is using hydroboration rare earth, alkoxy rare-earth, aryloxy group rare earth, trifluoromethanesulfonic acid rare earth, substituted benzoyl acid rare earth, rare earth carboxylate and rare earth halide as catalyst, compound to contain polyepoxy is catalyzed tetrahydrofuran ring opening polymerization as initiator, it is reacted 5 minutes to 5 days at a temperature of 30 DEG C to 80 DEG C, prepares hyperbranched poly tetrahydrofuran.Rare earth catalyst used in the present invention is in extensive range, it is cheap easily prepare, there is higher catalytic activity, it is up to hundreds thousand of to prepare the ptmg molecule amount of gained, and the degree of polymerization may be up to thousands of to tens thousand of, and the degree of branching is controllable. |
