    摘要: The invention relates to a method for modifying and crosslinking polybenzimidazole, PBI. The polybenzimidazole reacts with a compound, which has a halogen and a double-bond functionality and which comprises a halogen and an organic group, into modified polymers by means of a nucleophilic substitution of the amine proton of the benzimidazole functionality in a solution, and a functional group is connected via each resulting free double bond and/or the polymers that are thus modified are crosslinked.
