ABSTRACT:
Highly-purified monomers for poly(p-methylenebenzoate) polymers and poly(m-methylenebenzoate) polymers are prepared by purifying acetoxylated hydroxymethylbenzoic acid compounds derived by side-chain acetoxylation of toluic acid compounds. The purification process can be by recrystallation or by fractional distillation.
