Abstract: A method for bonding a material to a first substrate surface that includes providing a catalyst at the first substrate surface and then contacting that surface with a material that undergoes a metathesis reaction to bond the material to the first substrate surface. There are two embodiments of this method—a coating process and an adhesive process. In the coating embodiment, the metathesizable material is contacted with the catalyst on the substrate surface so that it undergoes metathesis polymerization to form the coating. The adhesive process includes (a) providing a catalyst at the first substrate surface, (b) providing a metathesizable material between the first substrate surface and the second substrate surface, and (c) contacting the catalyst on the first substrate surface with the metathesizable material so that the metathesizable material undergoes a metathesis reaction and bonds the first substrate surface to the second substrate surface.

Abstract: A corrosion inhibiting composition is provided. The composition comprises an intrinsically conductive polymer, e.g. polyaniline or polypyrrole, blended in a binder material, preferably a non-thermoplastic matrix, the blend being capable of adhering to a metal surface to provide enhanced corrosion resistance to the metal.

C. or higher, providing a tough, adhesive polyimide film that can catalyze electroless deposition.

Abstract: Radiation transmission control films comprising closely spaced agglomerates of small particles, e.g. in linear, side-by-side louvers, in a solid matrix where the agglomerates exhibit different radiation permeability than the matrix. Methods of making such films include magnetically aligning particles into louvers in an uncured matrix then curing the matrix to provide louvered film. Such films are useful to control the transmission of light, other electromagnetic radiation and particle radiation.

Abstract: Molded articles comprising fiber reinforced polyether modified styrene polymer wherein the weight ratio of glass fiber to styrene polymer is in the range of about 55:45 to about 75:25. The molded articles are prepared by a transfer molding process in which glass fiber mat containing 1 to 5 weight percent of an unsaturated polyester binder is impregnated with styrene monomer mixture containing an unsaturated polyether and the mold is subjected to conditions which induce fast polymerization of the monomer mixture. The molded articles possess resistance to heat distortion.
