Dataset for "Comparison of Cyclic and Linear Poly(lactide)s Using Small Angle Neutron Scattering"



Neutron scattering data of various cyclic and linear poly(lactide) samples (PLA). Samples were measured in solution at 1 wt% in deuterated acetone and THF over a q range of up to 0.003 to 0.53 Angstroms^-1. Data measured at Institut Laue Langevin (ILL), Grenoble, France Molecular weights range from 18,330 to 74,441 g mol^-1, with cyclic and linear samples generally having comparable molecular weights (i.e. weights of samples C1 and L1 are similar). This data allows for in depth comparison of novel cyclic and linear polymers at different temperatures, solvents, molecular weights and microstructures of PLA (given the chiral centre of lactide we were able to compare heterotactic, atactic PLA and isotactic PLLA).

Specifically, this dataset contains intensity and q data which can be plotted in its current form or fitted to various models to give data about polymer-solvent interactions and scaling exponents among other information.
