Abstract

Surface second harmonic generation is used to study surface reactions during photopolymerization of vinyl monomers on metal surfaces. Photopolymerization shows promise in making defect-free insulating and abrasion resistant coatings, and in the fabrication of microelectronic devices¹. Although researchers have studied the gas phase reaction in some detail, little is known about the surface reactions². Also, the effects of various physical parameters such as monomer pressure, light intensity, and the nature of metal and the monomer on the physical properties of polymer films are not known.
