Melt processing of cellulose nanocrystal reinforced polycarbonate from a masterbatch process
TL;DR: In this article, cellulose nanocrystal (CNC) reinforced polycarbonate (PC) nanocomposites were obtained by melt extrusion, which was then diluted by extrusion water from the CNC aqueous dispersion was exchanged to pyridine, and the mixture was precipitated in water.

Solid-State Polymerization of Polycarbonates Using Supercritical CO2
TL;DR: In this article, the authors report the extension of the crystallization process with supercritical CO 2 to granules or beads of low molecular weight polycarbonate in an effort to create a material that can undergo slid-state polymerization without using toxic organic solvents.

Polymer Crystallization By Chemical Nucleation
TL;DR: In this article, the mechanism of action of organic nucleating agents such as sodium benzoate and its derived salts completely differs from the generally accepted model, at least in the case of polyesters.
