Why do acrylates polymerize faster than methacrylates?Signs & Symptoms of Allergies to Methyl Methacrylate

I was curious as to why acrylates polymerize faster than methacrylates? Also, during copolymerization of acrylates and methacrylates, why do methacrylates homepolymerize first and then acrylates .Methyl methacrylate, or MMA, is a substance used in the manufacture of a variety of plastics and other products MMA is used widely and can be found as an additive in concrete, in adhesives, artificial joints, dentures, hairspray, nail polish, paints, textiles and windows MMA can cause contact irritation and allergic reactions in the skin, but does not appear to provoke allergic reactions in.
