Process for production of poly(lactic acid)-type resin, and poly(lactic acid)-type prepolymer |
| abstract |
A method of producing a poly(lactic acid) resin includes carrying out direct polycondensation using lactic acid as a main raw material to prepare a crystallized prepolymer having a weight average molecular weight of 5,000 to 25,000, an enthalpy of fusion ΔHm of 50 to 65 J/g and an acid value A mol/ton satisfying (1) below:n n450/(Mw/10,000−0.14)< A <950/(Mw/10,000−0.14) (1)n n(wherein Mw represents weight average molecular weight of the crystallized prepolymer); and subjecting the crystallized prepolymer to solid-phase polymerization. |
