FUNCTIONALIZATION OF POLYSTYRENE AND ADHESION STUDIES

The adhesion capability of novel functional polystyrenes to metals and their capability to provide corrosion resistance to metals under vari ous conditions have been investigated. The polyfunctional polystyrenes were prepared via reaction of the polystyrene with different function al groups [2-methyl-2,3-epoxy-6-octene-4-one (I), 2-methyl-2, 3-epoxy- 5,7-nonadien-4-one (II), 1-chloro-2,3-epoxy-5-chloromethyl-5-hexene (I II), 1-(Delta(3)-tetrahydrobenzaldoxime)-2,3-epoxy propane (IV), and m aleic anhydride (V)] in the presence of catalysts. The results show th at the addition of functional groups to the polystyrene increases its adhesion capability and corrosion resistance. This increase is attribu ted to the quantity and nature of the functional groups bonded to poly styrene.
