## Abstract The viscosity functions of long‐chain branched metallocene‐catalyzed ethene homopolymers and copolymers (LCB‐mPE) were described by an extended Carreau‐Yasuda model. The two characteristic relaxation times, __Ξ»__~1~ and __Ξ»__~2~, and the slope of the viscosity function between these two
