Versuchsvorschrift

Example 1 was repeated except that a mixture of methacrylic acid, ethylbenzene and 100 ppm, based on methacrylic acid, of p-methoxyphenol was used instead of the methacrylic acid/ethylbenzene mixture fed to the second and third polymerization vessels. Styrene/methacrylic acid copolymer was obtained at a rate of 3.2 kg per hour.
