Abstracts

EN

Some most representative results for semicrystalline polymers by positron annihilation spectroscopy method, showing the influence of crystallinity and morphology of samples on positron annihilation characteristics, are reminded. The latest finding of the author's experiment on modified polyamide 6 is presented. The latter reveals that the interfacial zone between a lamella and an amorphous region may influence the ortho-positronium characteristics. The role of chain defects is stressed.
