Synthesis and Self-assembling of Wholly Aromatic Block Co-oligomers:Oligo(ether sulfone)-b-oligo(ether ketone)with Sulfonic Acid Terminal Groups

摘要

Photo-induced acid-catalyzed crosslinking systems have been widely studied by many workers.The highly sensitive photocrosslinking materials can be used as negative-type photoresists,coating materials and printing materials.Epoxides and polymers containing cyclic ether units are cationically or anionically crosslinkable.Photocrosslinking of these compounds can be accomplished by the photolysis of initiator molecules,followed by reactions of the resulting photoproducts with cyclic ethers.Photoacid generators and photobase generators can be used as an initiator for the photoinduced crosslinking.
