Competition between crystal growth and intracrystalline chain diffusion determines the lamellar thickness in semicrystalline polymers

Abstract

The mechanism of crystal thickness selection in semi-crystalline polymers is unclear but intracrystalline chain diffusion has been shown to have a role. Here, the authors report on observations related to poly(oxymethylene) with slow intra-crystalline chain diffusion to fill the knowledge gaps between fast and absent diffusion systems
