Abstract
Compositions of a semicrystalline thermoplastic and a dispersed phase of an organically modified clay are disclosed, as well as a process for making the organically modified clay, which comprises contacting the clay with at least one imidazolium salt having two long alkyl chains, or a benzimidazolium salt having two long alkyl chains in the presence of a solvent, and recovering the organically modified clay having a d-spacing of clay intercalates of at least 28Å and thermal stability at 300°C.File in questo prodotto:
