US 4,062,886 A · Fluorenone carboxyle acid esters

Abstract

Disclosed are monomers of the formula: ##STR1## WHEREIN R is ##STR2## R' is hydrogen or methyl; R" is alkyl of 1-10 carbon atoms; X and Y are independently selected from the group consisting of NO.sub.2, halogen, cyano and --CF.sub.3 ; Z is oxygen or dicyanomethylene; a and a' can range from 0-3; and n is 1-10. These monomers can be readily polymerized to polymers suitable for use in electrophotographic imaging members and methods.
