Abstract: An anti-biofouling casing for a seismic streamer is described, the anti-biofouling casing comprising a polymer system comprising a hydrophobically-modified base polymer, the hydrophobically-modified base polymer comprising a base polymer having a backbone and a hydrophobically derivatized chain extender coupled to said backbone of said base polymer, wherein the the hydrophobically derivatized chain extender comprises a hydrophobic moiety. The anti-fouling casing comprises a hydrophobic surface to which a layer—such as a coating or a paint—of a material having low surface energy may be coupled to provide an anti-biofouling layer on the seismic streamer.
