| titleOfInvention | method for producing a crystallized poly (lactic acid) resin and crystallized poly (lactic acid) prepolymer pellet |
| abstract | method for producing a poly (lactic acid) resin and crystallized poly (lactic acid) prepellet pellet is a method for producing a poly (lactic acid) resin, the method comprising the steps of: perform direct polycondensation using lactic acid as a primary raw material to prepare a crystallized prepolymer that has an average molecular weight of 5,000 to 25,000, a melting enthalpy of 50 to 65 j / g and an acid to mol value / ton that satisfy the inequality (1) below: 450 / (mw / 10,000 - 0.14) <to <950 / (mw / 10,000 - 0.14) (1) (where mw represents the average molecular weight of the said crystallized prepolymer); submit the crystallized prepolymer to solid phase polymerization. a method for producing an aliphatic polyester resin that has a high molecular weight and, in a preferred embodiment, that has a high melting point as well as excellent thermal stability and shade can be provided. |
