Data for: The thermo-optical coefficient as an alternative probe for the structural arrest of polymeric glass formers

The data is supplementary to the publication "The thermo-optical coefficient as an alternative probe for the structural arrest of polymeric glass formers", DOI: 10.1016/j.polymer.2024.126868, and contains processed raw data.

Key words: Temperature-modulated optical refractometry, Solidification, Glass transition temperature, Thermo-optical coefficient, Structural arrest

The data sets contain measured data on Temperature-modulated optical refractometry (TMOR) of a model epoxy polymer from the viscoelastic temperature range, through the glass transition to the glassy state. The data sets were collected via the temperature-jump method.

Material details:

Bisphenol A Diglycidyl ether (DGEBA, DER332, CAS 1675-54-3) + Difunctional and trifunctional carbocylic acids (Pripol1040, Croda) +1,5,7-triazabicyclo[4.4.0]dec-5-en (TBD, CAS 5807-14-7, 10 mol-% relative to carboxylic acid functions)
