✦ Synopsis

Neutron reflectivity (NR) measurements have been used to investigate the interfacial composition profile between immiscible semi-crystalline polymers, from which values for the Flory-Huggins x parameter and interfacial tension can be obtained. In addition, measurements of small molecule ingress into high molecular weight polymers, have successfully been performed in-situ in real time. In both cases, special sample environment equipment has been used.
