Rheological and Mechanical Properties of Poly(methyl methacrylate) Associated with Lithium Salts

On the basis of lithium electrolyte mechanism, modified glassy polymers were developed by adding salts to poly(methyl methacrylate) (PMMA). This review summarizes how rheological and mechanical properties PMMA changed introducing various salts: perchlorate (LiClO4), trifluoroacetate (LiCOOCF3), trifluoromethanesulfonate (LiCF3SO3), nonafluorobutanesulfonate (LiC4F9SO3), bromide (LiBr). It was found that are dominated aggregation state in matrix, degree bulkiness anions, anion size. focused on “pinning” effect, which is attributed ion-dipole interaction between cations molecular chains. pinning effect evaluated molten during molding, directly affects solid state. Therefore, pinning, depends species, not only properties, but also tensile PMMA/Li-salts.
