Abstract
In order to synthesize benzoyl peroxide functionalized polystyrene (PSt), p olyisoprene (PI) and poly(methyl methacrylate) (PMMA), anionic living PSt, PI, and PMMA were allowed to react with an excess amount of 4-(bromomethyl) benzoyl tert-butyl peroxide (BMtB) or bis[3,5-bis(bromomethyl)benzoyl] pero xide (BDBP) in tetrahydrofuran (THF) at -78 degrees C. The results indicate that coupling reactions leading to dimers are significant during the react ion. Dimer formation was avoided when the living polystyrene was modified t o the alcoholate anion by reaction with ethylene oxide (EO).
