Abstract
A method for forming a monomeric carbonate includes the step of combining a monofunctional alcohol or a difunctional diol with an ester-substituted diaryl carbonate to form a reaction mixture. Similarly, a method for forming a monomeric ester includes the step of combining a monofunctional carboxylic acid or ester with an ester-substituted diaryl carbonate to form a reaction mixture. These methods further include the step of allowing the reaction mixtures to react to form a monomeric carbonate or a monomeric ester, respectively.
