System for Visible Photopolymerization of Bisphenol A Diglycidyl Ether

Faculty Mentor: Thomas W. Nalli

Tris(2,2,2-trifluoroethyl) phosphite (P(OCH₂CF₃)₃), bis(4-tert-butylphenyl) iodonium hexafluorophosphate, and phenylazoisobutyronitrile (PAIBN) (PhN=NCMe₂CN) have been shown to function as coinitiators of the photoinduced polymerization of cyclohexene oxide. The photolysis of PAIBN (λ_max = 395 nm) initiates a radical chain reaction of the phosphite with the iodonium salt to form polymerization- starting aryltrialkoxyphosphonium salt, thus allowing the use of visible light to start the cationic polymerization. My research focused on whether this system can be used for photopolymerization of the commercial monomer, bisphenol A diglycidyl ether.
