Key Points

This research aims to explore the formation pathways of isocyanurates in polyurethanes using a combined DSC-NMR methodology.
Employs differential scanning calorimetry (DSC) and nuclear magnetic resonance (NMR) techniques.
Analyzes the impact of chemical composition on the properties of rigid polyurethane foams.
Identifies distinct formation pathways for isocyanurates in different polyurethane formulations.
Demonstrates a direct correlation between chemical composition and the resultant network structure.

Implication

Reveals pathways of isocyanurate formation in polyurethanes, indicating composition impacts material properties.

Abstract

Polyurethanes (PU) are a versatile class of polymers whose properties can be tuned through chemical composition and network structure. Among these materials, rigid PU foams, formed from polyols and isocyanates...
