Reactive derivatives of HS-group-containing polymers

摘要

A novel class of reactive derivatives of polymers containing HS-groups is disclosed in which derivatives a number of the HS-groups are converted to a disulphide group of the formula -S-S-A-Z, where A is a hydrocarbon residue having 1-10 carbon atoms and Z is a group or acid addition salts of the last mentioned group, where n is 2 or 3, R1 is 2-pyridyl, 5-nitro-2-pyridyl or 4-pyridyl and R2 is methyl or ethyl. The novel derivatives may be used, for example, as thiolating agents or as carriers for e.g. enzymes or other proteins etc.
