This invention relates to an improved process to produce composite polymeric materials and an article having an adherent surface layer. More specifically, the invention describes a process for producing a modifying adherent layer on a passive polymeric material, the layer comprising a fluorinated ester substituted alkoxy cellulose having, on the average, between about 1.0 to 2.99 of the three reactive hydroxyl groups of each glucose unit present as alkoxy groups, and the remainder of between about 0.01 to 2.00 of the reactive hydroxyl groups of each glucose unit present as a fluoroester group of the formula: ##STR1## wherein R.sub.f is branched perfluoroalkyl comprising 3 to 20 carbon atoms; or --(CF.sub.2).sub.n CF.sub.2 --Q, wherein Q is hydrogen or fluorine, n is an integer from 1 to 19; or ##STR2##
