Linear poly(l‐lactides) (PLLAs) and poly(d‐lactides) (PDLAs) with Mn in the range 2000 − 4300 containing a different number and placement of carboxyl groups were obtained via cationic ring‐opening polymerization and post‐polymerization functionalization. PLA stereoisomers (PLLA‐(COOH)x and PDLA‐(COOH)x, where x = 1 − 3) were used for the investigation of stereocomplexation in solution performed in...
Poly(l‐lactic acid) (PLLA) was blended with a series of four‐armed poly(ϵ‐caprolactone)‐block‐poly(d‐lactic acid) (4a‐PCL‐b‐PDLA) copolymers in order to improve its crystallization rate and mechanical properties. It is found that a higher content of 4a‐PCL‐b‐PDLA copolymer or longer PDLA block in the copolymer lead to faster crystallization of the blend, which is attributed to the formation of stereocomplex...
