FIELD: chemistry.
SUBSTANCE: present invention relates to degradable cross-linking agent, which is used in production of polymers, of formulae: (a) (b)
(c)
where Photo1 and Photo2 represent photo-reactive group, n is integer between 1 and 10; and R1-R4 in formula (a) independently denote benzophenone group, hydroxyl group or its sodium, potassium or lithium salt, R denotes photo-reactive, hydroxyl group or its sodium, potassium or lithium salt; Y denotes linker, which is absent, or is amine, ether, straight or branched C1-C10alkyl, or combination thereof; and R1 and R2 in formula (c) are independently photo-reactive group, alkyl, hydroxyl group or its sodium, potassium or lithium salt, photo-reactive group is selected from benzophenone residue, or hydroxybenzophenone residue 3 or hydroxybenzophenone residue 4.
EFFECT: proposed is new effective degradable cross-linking agent.
