## Abstract The suitability of different types of telechelic poly(lactic acid) (PLA) copolymers for dilactide production and prepolymer products was evaluated. L‐lactic acid (L‐LA) was copolymerized with 1,4‐butanediol, pentaerythritol, adipic acid, or 1,2,3,4‐butanetetracarboxylic acid (1,2,3,4‐BT

We have studied how different catalysts and diols affect the properties of low-molecular-weight ( M w (GPC) õ 49800 g/mol) lactic-acid-based telechelic prepolymers. The catalysts and diols were tested separately in our previous studies. In this study, we used the best previously tested diols and cat
## 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
