Research Data for "Beyond macrophotoinitiators: hyperbranched polyethylene as multifunctional macromer for 3D printing "

Context and methodology

This dataset was created from original work conducted in the framework of a PhD project at University of Chemistry and Technology Prague and a CEEPUS-Exchange to TU Wien, and compiled in a publication. It provides the raw data of results presented and discussed therein. 

Technical details

In the following, description of the uploaded data is available. Detailed experimental procedures to arrive at the materials is included in the corresponding publication but abbreviations of formulations and materials used in the files are also described below.

Folder "NMR spectra"

Contains 1H, 13C and HSQC NMR spectra of the compounds UnBP and UnIC and 1H NMR spectra of compounds PE-BP1, PE-BP2, PE-BP3, PE-BP4, PE-IC1, PE-IC2, PE-IC3 and PE-IC4.

NMR files require the software MestreNova or TopSpin to open, which are community standard softwares for this data type.

Excel File "Figure Data"

The file tabs are named according to the corresponding figure displaying the data in the manuscript and the data type displayed:

Tab 1: Figure 2 UV-Vis spectrum

Tab 2: Figure 4a Photo-dynamic scanning calorimetry (Photo-DSC)

Tab 3: Figure 4b PhotoDSC

Tab 4: Figure 5 Dynamic mechanical thermal analysis (DMTA) IBA series

Tab 5: Figure 5 DMTA MIX series

Tab 6: Figure 5 DMTA TDD series

Tab 7: Figure 6 Tensile testing curves IBA series

Tab 9: Figure 6 Tensile testing curves TDD series

Folder "GPC"

Size exclusion chromatography (SEC; gel permeation chromatography, GPC) data for the (functionalized) hyperbranched polyethylene macromonomers. Data is given in Malvern™ native formats including calibration files. To open the files, the Malvern™ software OmniSEC is required. Additionally, PDF reports are included for each of the samples.

Folder “GCMS”

Gas chromatography with mass spectrometric detector data for the leeching tests of prepared materials. Data is given in “.raw” format and can be opened by the softwares MestreNova or OpenChrom, which are community standard softwares for this data type.
