Abstract

Abstract:Solid-state shear pulverization (SSSP) can lead to in situ mechanochemistry and enhanced dispersion relative to melt-state processes. SSSP of poly(ethylene terephthalate) (PET) results in low levels of branching and enhanced dispersion of heterogeneous nuclei, leading to increased melt viscosity and crystallizability, providing a solution to the problem of recycling PET for high-value applications. (PET undergoes molecular weight reduction during melt processing.) Adding 1 wt% microcrystalline cellulose to poly(lactic acid) (PLA) via SSSP can lead to major enhancements in crystallizability and materials with increased heat distortion temperature relative to neat PLA.
