Methyl Methacrylate → HCID 22173653, compound

Participants

Reaction Steps

To a monomer mixture including 89.2 parts by mass of methyl methacrylate, 5.8 parts by mass of methyl acrylate and 5 parts by mass of xylene, 0.0294 part by mass of 1,1-di-t-butylperoxy-3,3,5-trimethyl cyclohexane and 0.115 part by mass of n-octylmercaptan were added and uniformly mixed therein. The solution was continuously supplied to a sealed type pressure resistant reactor having an inner volume of 10 L. Polymerization reaction is carried out at an average temperature of 130° C. for an average retention time of two hours while stirring, and then the reaction solution was continuously transferred to a storage tank with deaeration equipment connected to the reactor to remove volatile portions therefrom. The melted solution was further continuously transferred to an extruder to obtain pellets of a (methyl methacrylate-methyl acrylate) (b-1) copolymer.
