Notes:
Applications of poly(4,4-dimethyl-1-penten-3-one) (PBVK) and poly(3-methyl-3-buen-2-one) (PMIK) as initiators for UV curing were studied. The triplet state of PBVK was quenched by monomers but its rate was small compared with the low molecular model compound, 3,3-dimethyl-2-butanone. The α-cleavage quantum yield of PBVK was estimated to be ca. 0.5. The graft efficiencies of the resulting polymers were 0.5. The sensitivity of PBVK is greater than benzoin methyl ether under 313 nm of irradiation.
