## Abstract The effects of three different types of surfactant systems (ionic, polymeric, and electrosteric stabilizers) on the water sensitivity of poly(butyl acrylateβ__co__βmethyl methacrylate) latex films was examined. The water sensitivity was found to be strongly dependent on the surfactant s
Adsorption and electro-oxidation of carbon monoxide, ethylene, acetylene, and hydrogen sulphide on tungsten carbide, in solutions of these compounds in I N H,SO,, have been investigated. It was found that CO, C,H+, and C,H2 do not undergo adsorption and oxidation and do not affect adsorption and ele
