| titleOfInvention | Polylactic resin and manufacture method thereof |
| abstract | The present invention is a kind of manufacture method of polylactic resin, described manufacture method comprises the operation making crystallization prepolymer solid state polymerization, this prepolymer is the prepolymer using lactic acid units as main component, the optical purity (Ea) of this crystallization prepolymer is 60 ~ 94%, weight-average molecular weight is 5000 ~ 100000, and crystal melting enthalpy (Δ Hma) is 4 ~ 50J/g.By the present invention, formability when can obtain melt-processed is excellent, melt-processed time the polylactic resin of the excellent and hydrolytic resistance excellence of resistance to drawdown. |
