Abstract: An acrylate or methacrylate functional copolymerizable monomer which serves as an adhesion for emulsion polymers is disclosed. This monomer is the adduct formed by reacting an aminoalkyl alkylene urea with about 0.9 up to about 1.5 molar proportions of a saturated monoepoxide to consume most or all of one of the two amino hydrogen atoms available, and then reacting with about 0.8 up to about 2.0 molar proportions of a monoisocyanate having a single acrylate or methacrylate group in the presence of at least 0.02%, based on the total weight of the reactants present, of an inhibitor which retards the free-radical polymerization of ethylenic unsaturation, such as hydroquinone, and phenothiazine.

Abstract: An olefinic polymer composition is provided which comprises an olefinic polymer selected from homopolymers and copolymers made from aliphatic, ethylenically unsaturated monomers containing from 2 to about 10 carbon atoms; from about 100 to about 3,000 parts per million based on the weight of the total composition of a hindered phenolic stabilizer; and from about 100 to about 10,000 ppm based on the weight of the composition of a stabilizer selected from compounds of the formula: ##STR1## wherein M is 0 or 1; R.sub.1 and R.sub.2 are each independently selected from hydrogen or an alkyl group containing from 1 to about 20 carbon atoms.

Abstract: Conductive paint comprises an organic solvent having dissolved and dispersed therein a binder containing a thermosetting resin and a hydroquinone derivative which is a product resulting from reaction between a hydroquinone (polyhydric phenol) and a fatty acid having 10 to 20 carbon atoms, added to the thermosetting resin, metal powder as a conductive material, and preferably a fatty acid derived from natural oils and fats and having 10 to 20 carbon atoms. This conductive paint exhibits characteristics not inferior to those of the conventional Ag conductive paint, such as low specific resistance, high moisture resistance and high heat resistance, and is much less expensive than the conventional Ag conductive paint.

Abstract: A novel bis-imide matrix resin system comprising 50 to 95 percent by weight of ethylenically unsaturated bis-imides, preferably a low melting mixture of a major portion of maleimides of aromatic amines such as toluene diamine and methylene dianiline with a minor portion of maleimide of an aliphatic amine such as trimethyl hexamethylene diamine and 5 percent to 35 percent by weight of a diunsaturated low-temperature cross-linking agent such as divinyl benzene which gels the bis-imide at low temperatures. This reduces stress between the matrix resin and the surface of the reinforcing fiber, thus reducing the tendency to form microcracks. Room temperature stability is improved by the presence of 0.5 to 5 percent of an oxidation inhibitor such as hydroquinone. The resin is useful as a matrix resin for high performance, graphite fiber reinforced composites.CROSS REFERENCE TO RELATED APPLICATIONThis application is a continuation of Ser. No. 248,978, filed Mar. 30, 1981, now U.S. Pat. No.
