The cross-linking process consists of chemically joining two or more molecules. The bridge is constructed using a reagent (cross-linker) that contains at least two reactive end groups capable of binding to specific functional groups of the molecules to be joined.<\/p>\n

This process is useful for proteomic methods (protein bioconjugation) but also to improve the performance, durability and weatherability of polymers. Cross-linkers increase the molecular weight of the cross-linked polymer and, in doing so, modify the film cohesion, surface and interlayer adhesion, chemical, impact and scratch resistance of the resulting material.<\/p>\n

So, crosslinking involves a target functional group, available in the polymer chain, and a cross-linker that it is supposed to react with the target group in predetermined conditions.<\/p>[\/et_pb_text][et_pb_accordion _builder_version=”4.24.0″ _module_preset=”default” hover_enabled=”0″ global_colors_info=”{}” sticky_enabled=”0″][et_pb_accordion_item title=”Only a few functional groups within typical polymer chains are selectable targets for practical cross-linking methods.
