Abstract
The present invention provides a process for the decomposition of a polyester which can accelerate the reaction for decomposing the polyester to form monomers serving as raw materials or raw material derivatives. This process for the decomposition of a polyester is characterized in that the polyester is decomposed by solvolysis with methanol to form a dimethyl carboxylate and a dihydroxy compound, and these decomposition products are added to and mixed with a melt of the polyester for the purpose of decomposing the polyester by solvolysis.
