Polymeric pyridinium ylide and products from same
摘要:
Polymers containing pyridinium ylide moieties are subjected to actinic irradiation to convert the pyridinium ylide moieties to water-insoluble or hydrophobic N-acyl-diazepine polymers. The polymeric pyridinium ylides can be used for the waterproofing or hydrophobization of surfaces and for the production of printing plates, photoresists, printed circuit boards and the like.
