WebThis may seem too much if you are going over it first itme but one quick way of identifying these steps in radical halogenation is to keep track of the number of radicals: Initiation – goes from 0 radicals to two radicals. Propagation – goes from 1 radical to two radicals. Termination – goes from 2 radicals to 0 radicals. WebPoly (methyl acrylate) One of the most important acrylic polymers is poly (methyl methacrylate), or PMMA, which is sold under the trade names Lucite and Plexiglass. Poly (methyl methacrylate), PMMA. PMMA is a lightweight, crystal-clear, glasslike polymer used in airplane windows, taillight lenses, and light fixtures.
