Hydrolytic degradation of linear 2-arm and branched 4-arm poly(dl-lactide)s: Effects of branching and terminal hydroxyl groups

“Linear” 2-arm and “Branched” 4-arm poly(dl-lactide) [i.e., poly(dl-lactic acid)s, or PDLLA] with relatively low number-average molecular weights (Mn) in the range 0.7–2.2 × 104 g mol−1 were synthesized using ring-opening polymerization of dl-lactide with the initiator of tin(II) 2-ethylhexanoate (i...
