The sentence in the Introduction that reads “In this respect, we purposely studied a PLA commercial sample that contains a D,D-LA content as high as 10 wt% drastically limiting its crystallization properties.”
should read:
“In this respect, we purposely studied a PLA commercial sample that contains a D,D-LA content as high as 4.4 wt% drastically limiting its crystallization properties.”
Further mentions of the D,D-LA content of 10 wt% should also read 4.4 wt%.
The text under the Materials heading of the Experimental section
“PLA 4032D was characterized by an average molecular weight of 52,000 g mol-1, a polydispersity (Mw/Mn) of 1.9, and an L/D isomer ratio of 90/10.”
should read:
“PLA matrix (PLANW) was characterized by an average molecular weight of 130,000 g mol-1 (PS standards), a polydispersity (Mw/Mn) of 1.9, and a D-isomer content estimated to 4.4 wt%.”
Throughout the manuscript the term “PLA4032D should read PLANW”
The text under the heading Poly(lactide)/POSS nanocomposites
“As expected for highly amorphous polyester like the investigated PLA(90/10 L/D), a broad signal is observed on all WAXS spectra.”
should read:
“As expected for highly amorphous polyester like the investigated PLA(95,6/4,4 L/D), a broad signal is observed on all WAXS spectra.”
Further in the text, under this heading, the sentence:
“Due to some uncontrolled crystallization phenomena of this specific (90/10 L/D) PLA matrix, it was highly difficult to get reproductive results by DMTA.”
should read
“Due to some uncontrolled crystallization phenomena of this specific (95,6/4,4 L/D) PLA matrix, it was highly difficult to get reproductive results by DMTA.”
The text in the Conclusions that reads “The most relevant observation could be achieved on the crystalline properties of a selected PLA matrix containing 90 wt% L,L-LA and 10 wt% D,D-LA monomeric units randomly distributed along the chain, i.e., a poorly crystallizable polylactide.”
should read
“The most relevant observation could be achieved on the crystalline properties of a selected PLA matrix containing 95.6 wt% L,L-LA and 4.4 wt% D,D-LA monomeric units randomly distributed along the chain, i.e., a poorly crystallizable polylactide.”
The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
