Abstract
Understanding the interactions of the crystalline and the amorphous domains in semi-crystalline polymers, such as HDPE or PVDF, is a subject of ongoing research. Here, we apply terahertz time-domain spectroscopy to study the impact of the glass transition taking place in the amorphous phase on lattice modes associated with the crystalline domains.
