    Abstract: As a vehicle resin used for self-polishing antifouling paints, a vinyl polymer having a plurality of primary amino groups in the form of Schiff base in the molecule is used. The films of an antifouling paint containing this vehicle resin gradually release an aldehyde exhibiting antifouling activity from the Schiff base group upon hydrolysis with sea water, while the film gradually dissolves from the surface.

    Abstract: Pressure sensitive structural adhesive and sealant compositions comprising: (a) a polymer system comprising from 95 to 15 percent by weight of a telechelic polymer and from 5 to 85 percent by weight of a heterotelechelic polymer wherein at least one of the functionalities thereon is the same as the functionality on the telechelic polymer, and (b) a dual curing system wherein one element of the curing system cures the telechelic polymer and the common functionality on the heterotelechelic polymer and the other element cures the functionality on the heterotelechelic polymer but does not cure under the conditions required to cure the telechelic polymer to form a structural adhesive or sealant composition. In a preferred embodiment, the polymer system is comprised of a hydroxyl functional telechelic diol or polyol polymer and the heterotelechelic polymer is a monohydroxylated polydiene polymer which also has epoxidized olefin functionality. The dual curing system preferably is comprised of an isocyanate curing agent to cure through the hydroxyl groups at ambient temperatures to form a pressure sensitive adhesive or sealant and an amino resin to cure through the epoxy functionality upon baking to form a structural adhesive or sealant.

    Abstract: A primer composition and method for improving adhesion of polymeric material to metal ion containing substrate is provided. The primer consists of a solution of a polymer whose chain contains polar groups, such as carboxy, hydroxy, groups and the like, and non-polar monoethylenically unsaturated terminal groups. The primer is applied to the surface to be treated, the solvent evaporated and the polymeric material applied and cured in the usual way. The bond tensile strength of samples employing the primer composition is substantially increased as compared to the bond tensile strength of samples not employing the primer composition of this invention.
