Described herein are thermoplastic linear polymers containing recurring units of the formulae:
and
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-, -S02-, -0-, 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 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 -0- bond. Also, described herein is a process for preparing such polymers.
