Studies of polymer thermosets using scattering techniques — •Mats Johansson — Department of Fibre & Polymer Technology, KTH Royal Institute of Technology, SE-100 44 Stockholm, Sweden

Thermoset polymers are complex macromolecular structures where the macroscopic properties depend on several different structural features such as crosslink density, rigidity on a molecular level, and internal secondary bond interactions. The final thermoset structure not only depend on the in-going monomers structure but also how these form the network i.e. the polymerization process. The presentation will describe how a combination of scattering techniques and traditional physical and chemical characterization techniques can reveal new insights on the structure / property relationship for thermoset polymers. It is moreover demonstrated that this approach also can be used to monitor the network formation in-situ i.e. how the structures evolves on a nanoscale during polymerization.
