A 2,2,2,2‐factorial design was used for the irradiation‐induced polymerization of 1,1,3‐trihydroperfluoropropyl and 1,1,7‐trihydroperfluoroheptyl acrylates with a 2‐M.e.v. electron accelerator in order to more critically determine the effect of variables. From the data obtained, it is concluded that: ( 1 ) degassing, flame‐out, and time‐lapse are significant, dependent main effects for both monomers, and atmosphere is a significant, dependent main effect for the heptyl ester, ( 2 ) the atmosphere and flame‐out, degassing and time‐lapse, and flame‐out and time‐lapse interactions are independently significant for the propyl ester, whereas for the heptyl ester the atmosphere and flame‐out is independently significant, but degassing and flame‐out, degassing and time‐lapse, and flameout and time‐lapse are dependently significant, ( 3 ) the degassing, flame‐out and time‐lapse interaction is independently significant for the heptyl ester, and ( 4 ) experimental variables may be significantly interdependent.
