Abstract
Improvements introduced in the main patent object, that is in a procedure for the decondensation of poly (ethylene terephthalate) to terephthalic acid dimethyl ester, characterized in that the poly (ethylene terephthalate) is added zin compounds in finely formed form divided, suspended in methanol, especially zinc oxide or zinc salts of organic or inorganic acids, in an amount of 0.1 to 2% relative to the poly (ethylene terephthalate) employed.
