Abstract

We studied the effect of ultrahigh molecular weight (UHMW) polymer on the strain-hardening in uniaxial elongation using PMMA varying UHMW content. These samples were homogeneously blended by solvent casting method. The relation between UHMW components and uniaxial elongational viscosity are discussed.
