Several linear ethene/alpha-olefin copolymers with butene, hexene, octene, dodecene, octadecene, and hexacosene as comonomers were characterized in linear-viscoelastic shear flow. Creep and creep recovery measurements were used to obtain the zero shear-rate viscosity eta(0) and the steady-state elastic recovery compliance J(e)(0). The correlation between the zero shear-rate viscosity and the weight average molar mass eta(0)(M-w) established for metallocene catalyzed high density polyethylene (mHDPE) was found to be obeyed by all samples containing comonomer contents up to 29 wt%. For the linear steady-state elastic compliance J(e)(0) an increase with growing molar mass M-w or comonomer content w(c) was observed. (C) 2008 The Society of Rheology.
