Abstract

Stabilizers for acrylic and methacrylic esters comprising 4-alkoxy phenol with less than 4 carbon atoms in the 4-alkoxy group and substituted in one or both the 2 and 6 positions by a sec. or tert. alkyl group containing at least 4 carbon atoms (see Division C2), are present during polymerization of the esters. Examples describe the polymerization of methyl methacrylate syrups containing 2,6-di-tert.-butyl-4-methoxy - phenol, and 2,21 - dihydroxy - 3,31-di - tert. - butyl - 5,51 - dimethoxy - diphenylmethane using benzoyl peroxide and a ,a -azo-di-isobutyro-nitrile as catalysts. Other stabilizers mentioned are 2-tert.-butyl-4-methoxyphenol and 2-sec.-butyl-4-methoxyphenol.ALSO:Stabilizers for acrylic and methacrylic esters comprise a 4-alkoxyphenol containing fewer than 4 carbon atoms in the alkoxy groups, and substituted on one or both of the 2 and 6 positions with a secondary or tertiary alkyl group containing at least 4 carbon atoms. 4-Methoxy phenols are preferred, e.g. 2-tert-butyl - 2,6 - ditert - butyl-, and 2 - sec - butyl - 4-methoxyphenols; and others have a tert-alkyl in the 2-position and 2-hydroxy-3-tert alkyl-5-alkoxyphenyl methyl in the 6-position, e.g. 2,21 - dihydroxy - 3,31 - ditert - butyl - 5,51-dimethoxy - diphenylmethane. Examples describe the stabilization of methyl methacrylate by 2,6 - ditert - butyl - 4 - methoxyphenol; 2,21-dihydroxy - 3,31 - ditert - butyl - 5,5 - dimethoxy - diphenyl methane; 2 - sec - butyl - 4 - methoxyphenol; 2 - tert - butyl - 4 - methoxy phenol; n-butyl methacrylate with 2,6-di-tert-butyl - 4 - methoxyphenol; ethyl acrylate with 2,6 - ditert - butyl - 4 - methoxyphenol, and n-butyl acrylate with 2,6-ditert-butyl-4-methoxyphenol. The esters may be polymerized in the presence of the stabilizer.
