-12-1, Lifluoromethylstyrene is polymerized to 5() to 200 C, preferably 100 to 200'O, in the absence of an initiator or in the presence of a radical polymerization initiator of s x s: ts or less. It is produced by polymerizing CaljA'1. The polymerization reaction is rapidly carried out by heating, and bomber is produced in good yield. Moreover, when the reaction temperature is low (d), the polymerization rate is slow and the yield of polymer is low.
Although it is possible to use an initiator such as peroxide, dicumyl peroxide, azoin butyronitrile, etc., the polymerization reaction can still be carried out at the above reaction temperature even when no polymerization initiator is used. easily progresses at Vrc.
