Titanium alkoxide catalysts for polymerization of cyclic esters and methods of polymerization |
摘要 |
Titanium alkoxide catalysts for polymerization of cyclic esters such as LA and CL and methods of polymerization are disclosed. Titanium is known to be non-toxic and the various compounds described herein can catalyze cyclic esters to produce polyesters with controlled molecular weights and relatively narrow molecular weight distributions. In one embodiment, caged titanium alkoxides catalysts are used. The caged titanium alkoxides can be atranes or non-atranes.
