Abstract
Methyl methacrylate is efficiently transesterified with a heavy alcohol in the presence of (i) defined amounts of a lithium catalyst incrementally added to the reaction medium, and (ii) an azeotrope-forming compound which forms, together with the methanol produced, an azeotrope distilling at a temperature of less than about 60.degree. C.
