Abstract: 
Cationically polymerised and highly crosslinked epoxy thermosets containing partially crystalline polyols are observed. The network- and domain formation is characterised with regards to possible phase separation of the partially crystalline polyole component. After thermoanalytical and mechanical characterization of the polymers, a proposed molecular order of the polyole component was discussed to be responsible for the observed toughening of the epoxy polymers. Due to the phase separated morphology kovalently crosslinked polymers showing a shape-memory effect are prepared and characterised. The results are transfered on a thermoplastic polyurethane containing block copolymers of different crystallinities to observe the influence of crystalline interactions on a stretchable polymer.
