Abstract

A comparative study of the morphology of polyethylene glycols and polyethylene oxide with different molecular weights was carried out. It was established that increasing molecular weight results in an increase in the degree of crystallinity, melting temperature, and thermal stability of the polymers. All of the compounds studied exhibit an amorphous–crystalline structure regardless of their physical state.
