## Abstract A microwave‐assisted method of synthesizing high‐molecular‐weight PLA using SSA as green catalyst was developed. Yellowish PLA with $\overline M \_{\rm v}$ above 2.0 × 10^4^ g · mol^−1^ was obtained when the reaction was run at 260 °C within 60 min under microwave irradiation with 0.4 w

## Abstract The microwave‐assisted direct polycondensation of LA to synthesize PLA has been studied. Microwave irradiation strikingly accelerates the polymerization rate of LA compared to conventional heating. By use of a binary catalyst of SnCl~2~/__p__‐TsOH, PLA with a $\overline M \_{\rm w}$ of
## Abstract **Summary:** Stereoblock poly(lactic acid) consisting of D‐ and L‐lactate stereosequences can be successfully synthesized by solid‐state polycondensation of a 1:1 mixture of poly(L‐lactic acid) and poly(D‐lactic acid). In the first step, melt‐polycondensation of L‐ and D‐lactic acids is
