✦ Synopsis

Diacid Monomer. The diacid monomer with the nonamethylene spacer was prepared using the method reported in a previous a r t i ~l e . ~

Polymerization

Polyester 1 was obtained by melt-polycondensation of the corresponding monomers, the dicarboxylic acid, and the hydroquinone diacetate using zinc diacetate as catalyst. Yield 90%.
