Summary:12,476 AROMATIC POLYMERS CONTAINING KETONE GROUPS Described herein are thermoplastic linear polymers containing recurring units of the formulae: (I) , (II) , and (III) wherein R is independently hydrogen, C1 to C6 alkyl, or C4 to C8 cycloalkyl, a is an integer of 0 to 4, Z is independently -?-, -SO-, -S-, -SO2-, -O-, alkylene, cycloalkylene, arylene, alkylidene, or cycloalkylidene containing from 2 to 20 carbon atoms, with the proviso. that Z cannot be -?- when the connecting ether bonds 12,476 are in the para position to Z; n is independently an integer of from 1 to 5. The units are attached to each other by an -O- bond. Also, described herein is a process for preparing such polymers.
