Micro-Hardness of PBT Influenced by Beta Radiation [PDF]
MATEC Web of Conferences, 2016 Cross-linking is a process in which polymer chains are associated through chemical bonds. Radiation, which penetrated through specimens and reacted with the cross-linking agent, gradually formed cross-linking (3D net), first in the surface layer and then in the total volume, which resulted in considerable changes in specimen behaviour.
