Abstract

The interaction of transition‐metal halides with poly(methyl methacrylate) (PMMA) has been studied in the past and methyl halides are always observed as a product of the reaction. When CrCl3 is used as an additive for PMMA, only traces of methyl‐containing products are seen and these only at quite high temperatures. The principal volatile products consist of carbon dioxide, carbon monoxide, and monomer, while the nonvolatile residue contains a multitude of methylene and methine carbons. A mechanism is invoked by which the ester methyl is transferred to the polymer backbone in a concerted process.
