A caulking and sealing compound contains (a) 1 part by weight of an emulsion polymer A of an ester of an ethylenically unsaturated carboxylic acid having 3 to 5 carbon atoms and a monohydric aliphatic alcohol having 1 to 12 carbon atoms, said polymer being in the form of an at least 50% aqueous dispersion, (b) 0À25 to 2À5 parts of a practically anhydrous and solvent free emulsifiable polymer B which (b 1 ) has a K value of 10 to 70 and is a polymer of an ester of acrylic and/or methacrylic acid and a monohydric alphatic alcohol having 2 to 8 carbon atoms and/or of a vinyl alkyl ether having 1 to 4 carbon atoms in the alkyl radical and/or of butadiene or (b 2 ) has a K value of 5 to 40 and is a polymer of isobutylene and/or isoprene, (c) 0À5 to 2À5 times the weight of the polymers of conventional inorganic fillers and (d) 8 to 18% by weight of the composition of water. The composition may also contain an emulsifier, a protective colloid and 0À5 to 10% by weight of A and B of a urea-formaldehyde resin, which is preferably modified with a bisulphite. Suitable polymers A include copolymers of (i) nbutyl acrylate and acrylonitrile or methyl acrylate, (ii) decyl acrylate, methyl methacrylate and acrylic acid, (iii) 2-ethylhexyl acrylate, styrene and acrylic acid, (iv) 2-ethylhexyl acrylate and vinyl chloride, (v) 2-ethylhexyl acrylate, acrylonitrile, and/or methacrylonitrile, and acrylic acid and/or methacrylic acid and (vi) n-butyl acrylate, methyl acrylate and acrylic acid. Polymer B is, e.g. a copolymer of one of the specified esters with acrylonitrile and/or methacrylonitrile and/or acrylic or methacrylic acid, polyvinyl isobutyl ether, polyvinyl methyl ether, an oily butadiene homopolymer or copolymer with styrene and/or alpha-methyl styrene and/or isobutylene, polyisobutylene or an isobutylene-styrene copolymer. In Examples 1 to 10 polymer A is a 2- ethylhexylacrylate/acrylonitrile/acrylic acid terpolymer, which is compounded with (1) to (3) polyisobutylene or poly-(n-butyl acrylate), a sperm oil fatty alcohol-ethylene oxide condensate, asbestos and chalk; (4) polyisobutylene, the said condensate, quartz, talc and carbon black; (5) and (6) poly-(vinyl isobutyl ether) and (5) an isooctyl phenol-ethylene oxide condensate, chalk and quartz or (6) ethylene glycol, quartz, chalk, carbon black, talc and heavy spar; (7) and (8) a polybutadiene oil modified with maleic anhydride, the said sperm oil condensate, a lead drier and quartz; (9) and (10) a polybutadiene oil isomerized in the presence of iron carbonyl, the sperm oil condensate and (9) chalk and quartz or (10) chalk alone. The compositions in the other examples comprise (11) A-a vinyl propionate t.-butyl acrylate/ acrylamide copolymer and B-a copolymer of n-butyl acrylate and vinyl isobutyl ether; (12) A-an n-butyl acrylate/styrene/acrylic acid copolymer and B-a 2-ethylhexyl acrylate/ acrylonitrile/butanediol monoacrylate copolymer; (13) A-an ethyl acrylate/acrylic acid copolymer and B-poly-(n-butyl acrylate); (14) A-an n-butyl acrylate/acrylonitrile/butanediol monoacrylate / N - methylol methacrylamide/ acrylic acid copolymer and B-poly-(vinyl iso. butyl ether); (15) A-an n-butyl acrylate/ methyl acrylate/acrylic acid copolymer and B-poly-(n-butyl acrylate) and (16)A-an nbutyl acrylate/vinylidene chloride/acrylic acid copolymer and B-poly-(vinyl isobutyl ether). The other ingredients of Examples 11 to 16 are one of the aforesaid ethylene oxide condensates, chalk, and in some cases, quartz.

Abstract: Coated films and moulded articles of polyolefines are produced by subcoating the articles, whose surfaces have been pretreated with oxidising flames, oxidizing agents, by irradiation or by exposure to corona discharges, with polymers of ethylenically unsaturated polymerizable compounds, drying the subcoating, applying as top coating an aqueous dispersion of a copolymer of 80 to 97% by weight of vinylidene chloride and 3 to 20% by weight of another copolymerizable mono-olefine monomer and drying said top coating, wherein as subcoating there is applied an emulsion copolymer of 90 to 98% by weight of at least one polymerizable monoolefinic unsaturated compound and 2 to 10% by weight of at least one ethylenically unsaturated polymerizable N-alkylolamide compound. The N-alkylol-amide compound may be a N-methylolamide of a copolymerizable ethylenically unsaturated acid having three to five carbon atoms. The subcoating may be an emulsion copolymer of 90 to 98% by weight of at least one mono olefinic monomer selected from copolymerizable ethylenically unsaturated acids having three to five carbon atoms, their esters with alcohols having one to eight carbon atoms, their nitriles or amides, styrene, vinyl or vinylidene chloride, and vinyl esters of monocarboxylic acids having one to eighteen carbon atoms, and 2 to 10% by weight of at least one N-alkylolamide of a copolymerizable ethylenically unsaturated acid having three to five carbon atoms e.g. 90 to 98% by weight of at least one ester of a copolymerizable ethylenically unsaturated acid having three to five carbon atoms and an alcohol having one to eight carbon atoms and, possibly, at least one monomer selected from styrene, acrylic acid, methacrylic acid, acrylonitrile, and methacrylonitrile and 2 to 10% by weight of at least one N-methylolamide of a copolymerizable ethylenically unsaturated acid having three to five carbon atoms. The emulsion copolymer for the subcoating may have added to it 0.5 to 10% of its weight of at least one inorganic acid and/or organic acid and/or acid-reacting salts. The polyolefine may be a homopolymer or copolymer of monoolefins having 2 to 5 carbon atoms e.g. ethylene or propylene. The polyolefine may constitute a layer on a substrate e.g. nonwoven fabric, fabrics of natural and synthetic fibres, paper, cardboard, cotton cloth, and films or sheeting of semi-synthetic and synthetic materials. Solutions or dispersions of the copolymer of the subcoating may be applied by brushing, spraying, knife coating, rolling or trowelling.
