Abstract

As a new catalyst with simple structure

no ligands and low toxicity

bis(trimethylsilyl) amine zinc [Zn(HMDS)

]

has been used for ring-opening polymerization of lactide

which is of great scientific significance to expand its application in the biological field. In this work

the ring-opening polymerization of lac

tide

-LA and

-LA catalyzed by Zn(HMDS)

was investigated

and the polymerization activity

controllability

crystallization

and the thermal properties of the polymer were discussed. The results showed that the Zn(HMDS)

/BnOH catalytic system could achieve highly efficient and controllable ROP of lactide monomer

and the obtained polymers maintain high stereo-regularity with

greater than 0.99. The thermal properties of the polymer were analyzed by differential scanning calorimetry (DSC). It was found that the cold crystallization temperature (

)

glass transition temperature (

) and melting temperature (

) changed regularly with the increase of polymerization degree.
