Abstract:

Preliminary experiments were conducted to determine the conditions necessary to produce an adherent coating of grafted acrylic acid on various polymers. An interpolymer is formed increasing the thickness of the rubber up to 0.005 in., depending on the conditions of exposure. It is feasible to use acrylic acid as the grafting monomer in preparation for the fluorination. High pressures are not necessary to accomplish fluorination of the grafted acrylic acid. Preliminary experiments show that it is feasible to graft a partially fluorinated acrylic acid prepolymer to neoprene. Samples of treated neoprene were evaluated for coefficient of friction values at three different loadings. Values of the frictional coefficient as low as 0.161 have been achieved. An apparatus yielding frictional coefficient data as a function of wear time has been constructed. Author
