    Abstract: Polymers having low surface energy, e.g. fluorocarbon polymers, are rendered printable by conventional methods, e.g. offset printing, by incorporating a suitable particulate filler in the polymer, and shaping the filled polymer under conditions which result in the surface of the shaped polymer having irregularities which correspond to the particles of the filler. Suitable fillers comprise particles having at least two dimensions in the range of 1 to 40 microns; glass fibers are particularly satisfactory. Extruded insulating polymeric jackets for electrical components, e.g. strip heaters and wire and cable, can readily be marked by use of the invention.

    Abstract: A thermosetting coating composition which may have nonvolatile solids content as high as 60% or greater and which may be employed as an automotive topcoat. The composition, exclusive of pigments, solvent, reactive and non-reactive diluents and other non-reactive components, consists essentially of:(A) A binder composition consisting essentially of:(1) Between about 30 and about 75 weight percent of one or more low viscosity resins selected from hydroxy functional acrylic polymers, hydroxy functional polyethers and hydroxy functional polyesters, each of which (i) is substantially soluble in the solvent of the composition and (ii) has a number average molecular weight of between about 1000 and about 2500; and(2) Between about 70 and about 25 weight percent of one or more crosslinked dispersion polymers each of which is substantially insoluble in the solvent of the composition; and(B) An aminoplast crosslinking agent in an amount of between about 5 and about 40 parts per 100 parts of said binder composition. The crosslinked dispersion polymer is prepared by free radical polymerization of 0.5 to 3.5 weight percent of di-,tri- or tetravinyl monomers and 99.5 to 96.5 weight percent of at least one other copolymerizable monoethylenically unsaturated monomer, in the presence of (i) hydrocarbon dispersing liquid which is a solvent for the polymerizable monomer, but a non-solvent for the resulting crosslinked polymer, and (ii) polymeric dispersion stabilizer which is solvated by said dispersing liquid and associated with said crosslinked polymer so as to maintain a separation between particles thereof, thereby inhibiting coagulation of said particles, wherein polymerization is carried out at elevated temperature such that the dispersion polymer first forms and then is crosslinked.

    Abstract: A solution copolymer of styrene or vinyl toluene and allyl or methallyl alcohol is esterified with from 20% to 65% of the weight of the ester with ethylenically unsaturated monocarboxylic fatty acid containing from 8 to 22 carbon atoms. This ester is then copolymerized with monoethylenically unsaturated monomers including from about 2% to about 15%, based on the total weight of the final copolymer, of a monoethylenically unsaturated carboxylic acid to provide a copolymer which dissolves in water with the aid of a volatile base and which is particularly useful in pigmented latex paints.
