Methods of functionalizing a-halogenated hydroxy acid-based polymers and coupling a-halogenated hydroxy acid-based polymers are provided. Suitable a-halogenated hydroxy acid-based polymers include a-halogenated polyesters and a-halogenated acrylate-based inimers. Methods include coupling a-halogenated polyesters and functionalizing a-halogenated polyesters without polymer cleavage. Certain a-halogenated hydroxy acid-based polymers may be functionalized, crosslinked or, intiate polymerization by inducing the a-halogenated hydroxy acid-based polymers to make a dioxolenium ion intermediate. The a-halogenated hydroxy acid-based polymers may also be functionalized using a radical trap.
