Abstract
Disclosed is a resinous adhesion promoter comprising (a) a random copolymer having first and second constitutional monomeric units, the first units comprising halogen and/or a pendant organic group having six or more carbon atoms and the second monomeric units comprising an active hydrogen-containing functional group; and (b) one of either (i) a non-reactive adhesion promoter or (ii) a reaction mixture comprising a first component and a second component, at least one of the first and second components having functional groups being reactive with the active hydrogen-containing functional groups of the random copolymer.
