POLIMERI RAMIFICATI DI ACIDO LATTICO AD ALTA VISCOSITA' NEL FUSO E ALTA SHEAR SENSITIVITY E LORO NANO COMPOSITI

摘要

Disclosed is a polymer obtainable by bulk polymerization of lactide or lactic acid or a lactic acid copolymer obtainable by copolymerization of lactide or lactic acid with glycolide, glycolic acid and/or hydroxyacids in open or closed (cyclic) form in the presence of at least two organic and/or organic/inorganic chain regulators or a functionalized nanoparticle (nanosilica, montmorillonite).
