Question 5 (this is one question I really need help with) Methyl methacrylate is polymerized by free radical polymerization at 70 oC to form long polymer chains. (a) If benzoyl peroxide is used as the initiator for the polymerization of methyl methacrylate please write the chemical structures of the compounds formed during the initiation step of the polymerization. What would happen if the reaction is not heated at 70 oC? (b) Write the chemical structures of the polymers formed during the propagation and termination steps of the polymerization. (c) Write the trade name of the polymer formed by the polymerization of methyl methacrylate and two of its common applications.

Methyl methacrylate is polymerized by free radical
(a) If benzoyl peroxide is used as the initiator for the polymerization of methyl methacrylate please write the chemical structures of the compounds formed during the initiation step of the polymerization. What would happen if the reaction is not heated at 70 oC?
(b) Write the chemical structures of the
(c) Write the trade name of the polymer formed by the polymerization of methyl methacrylate and two of its common applications.
(d) If a polymer with degree of polymerization 100 is synthesized during the reaction, determine its molecular weight (in g/mol).
(e) If from the polymerization of methyl methacrylate a polymer of 20 mg is produced, calculate the moles of the monomer units in the sample. Also, given that methyl methacrylate is a liquid, calculate the monomer volume (in µL) which needs to be added in the reaction flask so to produce 20 mg of this polymer (dmethyl methacrylate= 0.945 g/mL).
