| titleOfInvention | A kind of production method of polylactic acid material |
| abstract | The invention discloses a kind of method of producing polylactic acid material, comprise the following steps: in the presence of a catalyst, the rac-Lactide class monomer of melting is carried out pre-polymerization at 110 ~ 150 DEG C, and monomer conversion is 40 ~ 50%; The prepolymer obtained in step I is carried out under adiabatic conditions polymerization further and obtain polylactic acid material, monomer conversion is greater than 95%.According to method and apparatus provided by the invention, processing unit is simple, for the production of polylactic acid material, has the advantages that technical process is simple, energy consumption is low and cost is low, and can realize serialization, be convenient to extensive stably manufactured, has broad application prospect. |
