Please write legibly thank you! 1. Give the detailed arrow-pushing mechanism for the free radical polymerization of methyl methacrylate. Show the initiation step and the addition of at least 2 monomers. You do not need to show a termination step, but do show the [ Jn notation of the final polymer. NEATNESS COUNTS heat poly(methyl methacrylate methyl methacrylate The initiator in this experiment, benzoyl peroxide, contains a weak 0-0 bond that undergoes homolytic cleavage at elevated temperatures. This leads to...
