This invention provides a process for producing 2H-1-benzopyran-2-ones (coumarins) from optionally-substituted o-halocinnamic acids or esters under polyester-forming conditions. When the coumarins contain appropriately reactive functional groups, and desired monomers are present, a colored or UV-absorbing coumarin/polyester copolymer is provided in one step.
