This project has 1 Developed practical methods for oxidizing the surface of low-density polyethylene film and introducing reactive organic functionality into this oxidized surface layer. 2 Explored new techniques for analyzing the surfaces of organic polymeric solids. Contact angle titration--the study of the contact angle of water on organic solids as a function of pH--has proved particularly useful and extremely surface sensitive. 3 Characterized a series of new phenomena occurring in thin organic surface layers, including thermal reconstruction of the surface a process during which functional groups in the surface migrate into the deeper parts of the polymer. 4 Examined the basic physical organic chemistry of wetting of organic solids. and 5 Applied the information from these studies to the synthesis of new interface-modifying agents, especially for adhesion promotion.
