Abstract:
A polymer comprising an acetal-containing monomer unit having the general structure I and at least one of the fluorine-containing monomer units-having the general structures II and III: wherein R1, R4, R5 and R6 are each independently selected from the group consisting of H, lower alkyl CH2CO2R10, cyano, CH2CN, and halogen, wherein R10 is selected from the group consisting of any alkyl cycloalkyl, aryl, arylalkyl, alkylenecycloalkyl, silyl or siloxy or linear or cyclic polysiloxane group; R2 is CHR11R12 where R11 and R12 are each independently selected from the group consisting of H, lower alkyl, cycloalkyl and aryl; A is selected from the group consisting of a substituted or unsubstituted alkylene, cycloalkylene, alkylenecycloalkylene and alkylenearylene; and R3 is selected from the group consisting of a linear, branched or cyclic fluoroalkyl group and SiR13R14R15 where R13, R14, and R15 are each independently selected from the group consisting of alkyl, cycloalkyl, aryl, arylalkyl, alkylenecycloalkyl, silyl, siloxy, linear or cyclic polysiloxane or silsesquioxane alkyl group; B is selected from the group consisting of an aryl, C(&boxH;O)â€”Oâ€”(CH2)x where x=0-4, lower alkyl, cycloalkyl, alkene cycloalkyl, silyl, siloxyl, or linear or cyclic polysiloxane group. R7 is selected from the group consisting of H or an acid sensitive group; R8 and R9 are each independently selected from the group consisting of H or â€”CN group; and y=0-4.
