    Abstract: 1357281 Ethylene-vinyl acetate copolymer coating compositions FARBWERKE HOECHST AG 15 Feb 1972 [16 Feb 1971] 6945/72 Headings C3G and C3P Aqueous coating compositions comprise (1) a mineral pigment, (2) a pigment dispersing substance, (3) a binder comprising an aqueous dispersion of a copolymer of ethylene, vinyl acetate and optionally one or more other monomers, and (4) 2 to 20 weight per cent based on the solids content of the copolymer dispersion of a graft polymer of a vinyl ester or vinyl ester and an unsaturated carboxylic acid on a polyalkylene oxide. The binder may also comprise conventional water-soluble binders such as casein, starch and polyvinyl alcohol. The pigment may be china clay, calcium carbonate, barium sulphate, titanium dioxide or satin white. The pigment dispersing agent may be a polyacrylic acid salt or polyphosphate. Examples describe the preparation of paper coating compositions comprising china clay; sodium salt of polyacrylic acid; -ethylene/vinyl acetate, ethylene/vinyl chloride/vinyl acetate or ethylene/vinyl pivalate/vinyl acetate copolymer dispersion; starch, casein or polyvinyl alcohol; and graft polymers of vinyl acetate or vinyl acetate and acrylic acid on polyethylene glycols.

    Abstract: A composition suitable for treating rayon textiles to improve their adhesion to vulcanizates of unsaturated amorphous terpolymers of ethylene, a second 1-olefine and an unconjugated polyene having 3-22 carbon atoms comprises an aqueous dispersion containing (a) an unsaturated amorphous terpolymer of ethylene a second 1-olefine and an unconjugated polyene with 3-22 carbon atoms which has been grafted with acrylamide and (b) 10-40% by weight based on the unsaturated graft terpolymer of a polymethylol phenol resin prepared from a phenol or substituted phenol and formaldehyde. The polyene used to prepare the terpolymer may be an acyclic diene with terminal double bonds, an acyclic diene with terminal and non-terminal double bonds, a cyclic diene or triene or an endo-cyclic diene. Grafting may be effected by reacting the terpolymer with acrylamide in the presence of a free radical polymerization initiator in an inert solvent, e.g. benzene, chlorobenzene or carbon tetrachloride, or in an aqueous dispersion. The polymethylol phenol resin may be produced in situ in the graft polymer dispersion, e.g. from resorcinol and formaldehyde.ALSO:The yarn guides and the needles of the invenregenerated cellulose cords, yarns and threads, with vulcanizates of unsaturated amorphous terpolymers of ethylene, a second 1-olefin and an unconjugated polyene having 3-22 carbon atoms is increased by a process comprising (a) treating the rayon textile with an aqueous dispersion containing (1) an unsaturated amorphous terpolymer of ethylene, a second 1-olefin and an unconjugated polyene with 3-22 carbon atoms which has been grafted with acrylamide and (2) 10-40% by weight based on the unsaturated graft terpolymer of a polymethylol phenol resin prepared from a phenol or substituted phenol and formaldehyde, (b) drying the textile, (c) embedding the treated textile in a vulcanizable mixture of an unsaturated amorphous terpolymer of ethylene, a second 1-olefin and an unconjugated polyene having 3-22 carbon atoms, sulphur and vulcanizing agent and (d) vulcanizing the composite structure. The polyene used to prepare the terpolymer may be an acyclic diene with terminal double bonds, an acyclic diene with terminal and non-terminal double bonds, a cyclic diene or triene or an endocyclic diene. The vulcanizing agent may be 2-mercaptobenzothiazole or tetramethylthiuram disulphide. The acrylamide-grafted terpolymer may contain 0.5-5/% by weight of acrylamide. The polymethylol phenol resin may be produced in situ. As a result of the treatment with the polymethylol phenol resin and graft terpolymer the textile may gain in weight by 1-15%. After treatment with the polymethylol phenol resin and graft terpolymer the textile may be dried in a drying tunnel at 140 DEG -240 DEG C for 20 minutes-5 seconds. After step (c) a further layer of a vulcanizable mixture comprising a saturated amorphous copolymer of ethylene and propylene or butene-1 may be applied and the composite structure then vulcanized.
