Abstract: The thermal behaviour of ethylene based (co)polymers, as revealed by (TM)DSC can be used as a product-fingerprint because it strongly depends on molecular parameters such as chain length, chain length distribution and branching. To properly understand DSC thermal behaviour, the concomitant changes in phase structure (morphology) and their relationships with the molecular structure and processing history were studied, using independent morphology-sensitive tools under conditions that are DSC-typical. SALLS and the real-time SAXS/WAXD synchrotron allowed for a morphological characterisation from the micrometer to the nanometer scale within time frames of a few seconds. The latter tools were optimised, and new methods for X-ray and light scattering data evaluation were developed. A molecularly well-characterised linear polyethylene, a homogeneous ethylene-l-octene copolymer and a binary blend of these components were investigated. The latter can be considered as a model system for linear low-density polyethylene.
