WebJul 1, 1982 · It is found that for butandiol and longer diol chain extenders (up to octandiol) the structure depends on whether the diol has an even or odd number of CH 2 groups. The even diol polymers adopt the lowest energy fully extended conformations that allow for hydrogen bonding in both directions perpendicular to the chain axis. WebThe poor melt strength of PLA plays a negative role in cell growth and mostly leads to cell wall rupture. 22, 23 To overcome the mentioned drawbacks, different modification techniques, including nanoparticle incorporation, 24 crosslinking, 25 copolymerization, 26 chain extension, 27 and producing PLA/polymer blends, 28 have been performed.
