These relate to polymer samples in the supporting information of the associated publication. 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. 2022-12-13 University of Bath public These data were collected on different polymer samples using neutron scattering techniques at Institut Laue Langevin (ILL), with the aim of characterising the physical behaviour of the samples in solution. Variables include two temperatures (15, 40 °C), two solvents (deuterated acetone and deuterated THF) and various polymers of different molecular weights and structures. The data can be used in its current form to give intensity vs. q plots, or fitted using various models to give other values.

All samples were dissolved in acetone-d6 or THF-d8 at 1 wt% and scattered neutron intensities were collected. Acetone is the θ solvent for PLA and THF is considered to be a “good” solvent for PLA, commonly used for routine analysis in GPC, MALDI-TOF etc. The sample-to-detector distance was varied between 1.7 and 8 m for all samples to cover a range of q from 0.018 to 0.52 Å⁻¹. For some samples, an additional sample-to-detector distance was employed to give low q measurements down to 0.003 Å⁻¹. The scattering variable q is expressed in terms of the neutron wavelength and scattering angle as q = (4π/λ)sin(θ/2) where the neutron wave-length was λ = 6 Å⁻¹. Absolute scattering intensities are given corrected for scattering from the empty sample cell, for detector efficiency and the presence of background intensity using standard methods. Software used to collect data is unique to ILL facility which uses a neutron source (Uranium). Similar facilities exist across the world (ISIS in UK for instance). Viewing the data requires only Excel and modelling can be done using SASview 5.04 (free software) as described in the associated publication (we used custom RPA models). https://doi.org/10.1021/acs.macromol.2c02020 en 1 10.15125/BATH-01203 https://doi.org/10.1021/acs.macromol.2c02020 pub open
