Polymer crystallization is a fundamental process influencing material properties, yet understanding the molecular intricacies preceding crystallization remains a challenge. This research builds on our prior work in generating unsupervised machine-learning labels for amorphous and crystalline phases in polymer crystallization [A. Bhardwaj, J.-U. Sommer and M. Werner, arXiv:2311.00454 (2023)]. Our focus extends to the exploration of the polymer melt, to quantify the latent information contained within its molecular conformations prior to crystallization. Through the analysis of the spatial distribution of molecular fingerprints, we characterize the subtle changes in molecular arrangements that precede the crystalline transition. Our study strives to advance the understanding of polymer crystallization, offering a new perspective for informed material design.
