# Bioplastic Thermal Property Data

Experimental polymer thermal-property data used to train the multitask
Tg / Tm / Td prediction models in the
[predictive_bioplastic_design](https://github.com/chakratech/predictive_bioplastic_design)
project.

## Contents

`experiment_polymer_data.xlsx` — experimental polymer records with PSMILES
strings and measured thermal properties (glass transition temperature Tg,
melting temperature Tm, decomposition temperature Td), among other columns.
