## Abstract The tensile drawing behaviour and the viscoelastic relaxations of three different copolymers of ethylene, containing 1βbutene, 1βhexene and 4βmethylβ1βpentene as comonomer, have been studied. The composition of the copolymers is increasingly poorer in comonomer following the above order
Dynamic mechanical measurements are reported on two polyethylene copolymers with different types of comonomers and well-characterized comonomer distributions. Measurements on both isotropic and oriented samples were undertaken over a wide frequency range. The mechanical anisotropy and activation ene
