Copolymers having pendant functional thymine groups

摘要

Multi-functional vinylbenzyl and vinylphenyl pendant thymine (and uracil) groups are disclosed. The monomers can be used for the production of polymers useful in photoresist and other compositions as a function of the crosslinking reactivity of the pendant groups. Images in polymer are provided by exposure to actinic radiation (e.g., UV), containing such polymer and by solvent removal of non-exposed regions.
