  • Norbornenylmethyl fluoroalkyl ethers
    Publication number: 20070191560
    Abstract: New monomers, norbornenylmethyl fluoroalkyl ethers, made by reaction of bicyclo(2,2,1)hept-5-ene-2-methanol with fluoro(alkyl vinyl ethers), are described. These monomers are useful in making polymers such as hydrophobic, hydrolytically-resistant polymers for photoresists, particularly for use in photoimaging by immersion lithography with 193 nm light.
