中文摘要	synchrotron small angle x-ray scattering was used to study the deformation mechanism of high-density polyethylene that was stretched beyond the natural draw ratio. new insight into the cooperative deformational behavior being mediated via slippage of micro-fibrils was gained. the scattering data confirm on the one hand the model proposed by peterlin on the static structure of oriented polyethylene being composed of oriented fibrils, which are built by bundles of micro-fibrils. on the other hand it was found that deformation is mediated by the slippage of the micro-fibrils and not the slippage of the fibrils. in the micro-fibrils, the polymer chains are highly oriented both in the crystalline and in the amorphous regions. when stretching beyond the natural draw ratio mainly slippage of micro-fibrils past each other takes place. the thickness of the interlamellar amorphous layers increases only slightly. the coupling force between micro-fibrils increases during stretching due to inter-microfibrillar polymer segments being stretched taut thus increasingly impeding further sliding of the micro-fibrils leading finally to slippage of the fibrils.
