Abstract: A method for recovering methyl methacrylate from a mixture of polymeric materials containing poly (methyl methacrylate) which comprises contacting the mixture with a boiling C.sub.5 - C.sub.8 alkane, separating an insoluble residue containing poly (methyl methacrylate) from the alkane and its extract, extracting poly (methyl methacrylate) from such insoluble residue with boiling acetone, separating the poly (methyl methacrylate) from the acetone, and recovering the methyl methacrylate monomer from such poly (methyl methacrylate) by pyrolysis. In a preferred embodiment, the poly (methyl methacrylate) containing solid obtained after the acetone extraction is compressed under elevated temperatures and pressures prior to pyrolysis. The method can be stopped prior to the pyrolysis step when it is desired to recover only the poly (methyl methacrylate).

Abstract: Disclosed is an improvement in the cooxidation process for making dimethyl terphthalate (DMT). In the cooxidation process an oxidate comprising monomethyl terephthalate and p-toluic acid is esterified with methanol to form a reaction mixture comprising DMT and methyl p-toluate, methyl p-toluate is separated from the reaction mixture, and p-xylene and said methyl p-toluate are cooxidized in the liquid phase with molecular oxygen to form more oxidate, which is esterified, etc. The improvement comprises separating p-toluic acid from part of the oxidate prior to esterifying the oxidate, and cooxidizing separated p-toluic acid with said p-xylene and said methyl p-toluate. This improvement results in a lesser quantity of oxidate subjected to esterification, and a reduction in the quantity of methyl p-toluate cooxidized with p-xylene.
