- ABSTRACT Polyurethanes are often produced by reacting a hydroxylated prepolymer with isocyanate crosslinkers. In order to obtain the prepolymer, a macrodiol is reacted with diisocyanate via the addition reaction between OH and NCO functional groups, so called chain-extension. During the experiments, two specific macrodiols were chain extended with two conventional diisocyanates as described in the proceedings article “Influence of aliphatic moieties in diisocyanates on chain extension kinetics of adipate macrodiols” Sandra Mačiulytė, Antanas Strakšys, S. Asadauskas, Proc. “Baltic Polymer Symposium 2019”, pg 40, Vilnius, Sept 20, 2019 http://www.bps2019.chgf.vu.lt/wp-content/uploads/2013/02/BPS2019_programme_and_proceedings2.pdf DOI: 10.5281/zenodo.3813463 . Additional values of isocyanate concentrations, which were measured during kinetic studies of the chain extension, are provided.
- DATASET This dataset contains the spreadsheet with the measured isocyanate concentrations along with the description of the procedures and metadata. This information is provided in the "Adhesive_Chain_Extension_WP5_Dataset_5-1.zip " file, which contains 3 compressed files: The spreadsheet file " Adhesive_Chain_Extension_WP5_Dataset_5-1.xls " contains measured NCO values, including those used for the figure Figure 1 in the proceedings article "Influence of aliphatic moieties in diisocyanates on chain extension kinetics of adipate macrodiols" Sandra Mačiulytė, Antanas Strakšys, S. Asadauskas, Proc. "Baltic Polymer Symposium 2019", pg 40, Vilnius, Sept 20, 2019 http://www.bps2019.chgf.vu.lt/wp-content/uploads/2013/02/BPS2019_programme_and_proceedings2.pdf DOI: 10.5281/zenodo.3813463 . Each sheet in the spreadsheet file represents the data for specific diisocyanate at different temperatures. The " Adhesive_Chain_Extension_WP5_Dataset_5-1_Experimental.pdf " file details the materials and experimental methods for the measurement of NCO values. Guidance is also provided on how to run the experiments in other laboratories. The " Adhesive_Chain_Extension_WP5_Dataset_5-1_Metadata.pdf " provides more detailed metadata information for this dataset.
