Observation of a transient structure prior to strain-induced crystallization in poly(ethylene terephthalate)
Abstract Using time-resolved X-ray diffraction at the European Synchrotron Radiation Facility we have observed a highly oriented weak transient diffraction peak which persists for about 0.2 s priorExpand
Influence of temperature and chain orientation on the crystallization of poly(ethylene terephthalate) during fast drawing
Abstract Three regimes of poly(ethylene terephthalate) (PET) deformation are identified from a detailed analysis of time-resolved wide angle X-ray scattering (WAXS) data recorded during theExpand
Real time SAXS/stress–strain studies of thermoplastic polyurethanes at large strains
Abstract Simultaneous small angle X-ray scattering (SAXS) and force measurements have been recorded during tensile deformation of two contrasting polyurethane elastomers. The elastomers comprise theExpand
Effect of draw ratio and temperature on the strain-induced crystallization of poly (ethylene terephthalate) at fast draw rates
Abstract Wide angle X-ray scattering (WAXS) data recorded during the drawing of poly(ethylene terephthalate) (PET) under industrial processing conditions was analysed in terms of changes in theExpand
Ultrasonic measurements related to evolution of structure in curing epoxy resins
Abstract The tracking of the cure of epoxy adhesives and the assessment of the cure state of adhesive bondlines joining engineering components are important for quality assurance during manufactureExpand
Orientation and crystallisation mechanisms during fast drawing of poly(ethylene terephthalate)
SummarySynchrotron radiation has been used to record the diffraction patterns from Poly(ethylene terephthalate) for a range of draw rates (0.1 to 10sec−1) and temperatures (90 to 120°C). The patternsExpand
Time-Resolved Simultaneous SAXS/WAXS of the Drawing of Polyethylene at the Daresbury SRS.
A system has been developed which represents a significant advance in the quality and extent of small- and wide-angle X-ray scattering data (SAXS and WAXS) that can be recorded simultaneously withExpand
Characterization of strain-induced crystallization of poly(ethylene terephthalate) at fast draw rates using synchrotron radiation
Abstract Structural changes during fast drawing of poly(ethylene terephthalate) were studied by wide-angle X-ray scattering using synchrotron radiation. Drawing was studied at 80, 90, 100 and 110°CExpand
Microfocus X-ray Diffraction of Spherulites of Poly-3-hydroxybutyrate.
This is the first report of the correlation of optical andX-ray measurements on spherulitic polymer films where X-ray diffraction patterns have been recorded and displayed continuously in real time while the specimen was tracked in steps of 10 mum across an incident X-rays beam with a diameter as small as 10 mum.

Orientation prior to crystallisation during drawing of poly(ethylene terephthalate)
Abstract Wide angle X-ray scattering data have been recorded during the drawing of poly(ethylene terephthalate) (PET) using a wide range of draw rates (0.05–12 s −1 ), temperatures (90–120°C) andExpand
