title: Designing of imine thiophene-ligated metal-complexes and implication in ethylene polymerization

description: Polyethylene is the single largest volume polymer produced globally using Ziegler-type catalysts. Numerous modifications have been reported in search of a better catalyst that can control molecular weight, polydispersity, and branching. In our attempts to identify a suitable imine thiophene-ligated chromium complex, we examined 9 different titanium complexes computationally. The DFT investigations considered barriers for insertion, propagation, and termination by β-H elimination or chain transfer, and identified N-(4-methoxyphenyl)-2-phenyl-1-(thiophen-2-yl)ethan-1-imine(L9) as the most suitable ligand. Subsequently, L9 was prepared in good yield (70%) by condensing 2-phenyl-1-(thiophen-2-yl)ethan-1-one with 4-methoxyaniline. Ligand L9 was treated with early transition metal precursors (Ti, Cr, Zr) to generate a homogenous catalyst. The identity of these catalysts was unambiguously ascertained using a combination of NMR, ICP, FT-IR, UV-Vis spectroscopy, and ESI-MS. The performance of L9-ligated titanium complex [Cat.1] was examined in ethylene polymerization using MMAO as a co-catalyst. Insertion of ethylene was tracked using high-pressure NMR experiments and Cat.1 was found to be active in the polymerization. Ethylene polymerization conditions were optimized to obtain high activity and molecular weight polyethylene. The chromium complex [Cat.2] outperformed the Ti and Zr-derived catalysts with the highest TOF of 6294 mol of PE/mol of Cr/h. Cat.2 produced high molecular weight, high-density polyethylene. Rational designing and synthesis of imine thiophene-ligated Ti, Cr, and Zr-complexes and their performance in ethylene polymerization is presented.

title: Synthesis and characterization of amphiphilic Poly(2-hydroxyethyl acrylate-g-α-Methyl-β-Alanine) by Nitroxide-Mediated Polymerization Using “grafting through” approach

description: Oligomeric poly(α-methyl-β-alanine)with vinyl end-group (PmBA) was synthesized <i>via</i> base-catalyzed hydrogen-transfer polymerization (HTP) of molten methacrylamide (MAm) in the presence of sodium <i>tert</i>-butoxide (t-BuONa). The PmBA was used as a comonomer in the synthesis of amphiphilic poly(2-hydroxyethyl acrylate-g-α-methyl-β-alanine) (PHEA-g-PmBA)<i>via</i> nitroxide-mediated polymerization (NMP)and "grafting through" approach.The graft copolymer formation was confirmed byproton nuclear magnetic resonancespectroscopy (<sup>1</sup>H-NMR), Fourier-transform infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), and static light scattering (SLS)measurements. Thermogravimetric analysis of the amphiphilicPHEA-g-PmBAexhibited a multi-step decomposition curve corresponding to the α-methyl-β-alanine and the 2-hydroxyethyl acrylate blocks at about 306, 369, and 403 °C.DSC curve of the copolymer has a baseline shift at −12.87 °C attributed to the glass transition temperature. SLS analysis of the final product resulted in a weight average molecular weight of 83.6 kDa. The spectroscopic and thermal analyses proved that amphiphilicPHEA-g-PmBA was successfully synthesized through HTP and NMP.

title: micro-XRCT data sets and in situ measured ultrasonic wave propagation of a pre-stressed monodisperse rubber and glass particle mixture with 30% volume rubber content

description: This dataset contains two micro X-ray Computed Tomography (micro-XRCT) data sets from scans of the identical cylindrical sample (diameter 80 mm; unloaded height 80 mm) under different uniaxial compression loads. The sample consists of monodisperse soft (rubber) and stiff (glass) particles mixture. Both particles have an identical diameter of 4 mm. The volume fraction of the rubber particles is 30 %. The scan was performed in a low X-ray absorbing transparent oedometer cell with an integrated pair of P-wave ultrasonic transducers to determine in situ the sample stiffness based on wave propagation velocity measurements. On both sides, the wave travels through a 10 mm long Poly (methyl methacrylate) (PMMA) pre-run and after-run section, before and after the wave enters and leaves the sample.
&lt;br&gt;&lt;br&gt;
The prepared sample inside the oedometer cell was uniaxially compressed in axial direction in subsequent force increments from F_stat. = 200 N to F_stat. = 1000 N (force-controlled) using a Universal Testing Machine (UTM) integrated into the XRCT system. At each force level, the system was relaxed for some time at the defined force to compensate the creep behavior of the soft particles. Subsequently, ultrasonic wave propagation measurements were performed at five different load levels, F_stat. = {200, 400, 600, 800, 1000} N. micro-XRCT scans were acquired in situ at F_stat. = {400, 800} N. For this, it was switched from force-controlled to displacement-controlled to avoid creeping and an eventual movement of the particles during the imaging. 
&lt;br&gt;&lt;br&gt;
In this data set, the reconstructed 3d volumes ("mixture_nu0.3_F400N_reconstructed.tar.gz" and "mixture_nu0.3_F800N_reconstructed.tar.gz"), as well as the projection images ("mixture_nu0.3_F400N_projections.tar.gz" and "mixture_nu0.3_F800N_projections.tar.gz") for both preloads are given. The raw ultrasonic measurement data (transducer signals over time) is provided for all five preloads ("mixture_nu0.3_ultrasonic_data.tar.gz"), before and after the force-controlled relaxation, as an averaged signal of a stack of 32 signals. The file "mixture_nu0.3_utm_data.csv" contains the measured axial force and displacement from the UTM during the whole experiment. Based on the measured displacement of the UTM, the current mixture length was determined. In the file “mixture_nu0.3_P-wave_moduli.csv” the final calculated P-wave moduli for the different preload levels are contained.
