Higher-order crystalline structures of poly(oxyethylene) in poly(d,l-lactide)/poly(oxyethylene) blends
2013
Polymer
Higher-order crystalline structures in blends of poly(lactide)/poly(oxyethylene) (PLA/PEG) were investigated using small-angle X-ray scattering (SAXS). For this purpose, the fact that two polymers are both crystalline makes situation much complicated. To simplify, we used non-crystalline PLA: poly(D,Llactide) (DLPLA), which is a racemic copolymer comprising D-and L-lactide moieties. Higher-order peaks arising from the ordered lamellar stacking of PEG (i.e. the lattice peaks) were observed in
