ABSTRACT:
In accordance with the present invention, there is provided a process for the production of deuterated acrylic acid or deuterated methacrylic acid comprising the exchange of hydrogens in acrylic acid or methacrylic acid with deuteriums in the presence of a catalyst. The deuterated acrylic or methacrylic acid is very useful as a starting material in the production of high quality optical plastic fibers.
