Local orientation measures by infrared dichroism and thermal stress measures by dilatometric analysis of image (DAI) have made it possible to quantify the evolution of the structure versus the thickness of the injected plastic parts. The stiffness local properties on the one hand, and thermal expans
## Abstract Timeβresolved fluorescence properties of 9βmethylanthracene (9MAn) dispersed in film of polyvinylchloride (PVC) containing carbon black were studied under tensile loadings. The fluorescence lifetime of 9MAn decreased from 5.70 to 5.55 ns, whereas the stresses acting on the films increas
