Mai farawa wanda GMA ke amfani da shi akai-akai don gyaran polyolefin ta hanyar GMA shine dicumyl peroxide (DCP). Wasu mutane kuma suna amfani da benzoyl peroxide (BPO), acrylamide (AM), 2,5-di-tert-butyl peroxide. Masu farawa kamar oxy-2,5-dimethyl-3-hexyne (LPO) ko 1,3-di-tert-butyl cumene peroxide. Daga cikinsu, AM yana da tasiri mai mahimmanci wajen rage lalacewar polypropylene lokacin da aka yi amfani da shi azaman mai farawa. Dasa GMA akan polyolefin zai haifar da canjin tsarin polyolefin, wanda zai haifar da canjin halayen saman polyolefin, halayen rheological, halayen zafi da halayen injiniya. Polyolefin da aka gyara na GMA yana ƙara polarity na sarkar kwayoyin halitta kuma a lokaci guda yana ƙara polarity na saman.
