Abstract: 869,434. Coated bituminized felt paper. BADISCHE ANILIN- & SODA-FABRIK A.G. Aug. 20, 1959 [Sept. 26, 1958], No. 28456/59. Class 140. A floor covering comprises a bituminized felt paper coated with a sealing composition containing an aqueous dispersion of a copolymer obtained by polymerizing a mixture of monomers of which each 100 parts by weight contains 20 to 90 parts by weight of vinylidene chloride, a maximum of 80 parts by weight of an acrylic acid ester and/or carboxylic acid vinyl ester, and a maximum of 40 parts by weight of vinyl chloride. The copolymer may be obtained by polymerizing 60 to 90 parts by weight vinylidene chloride and 10 to 40 parts by weight acrylic acid ester, carboxylic acid vinyl ester and/or vinyl chloride. Again, the copolymer may be obtained by polymerizing 60 parts by weight of vinylidene chloride and vinyl chloride i.e. a mixture containing at least 20 parts vinylidene chloride and up to 40 parts vinyl chloride, and 40 parts by weight of acrylic acid ester and/or carboxylic acid vinyl ester. Acrylic acid esters of aliphatic alcohols having 1 to 8 carbon atoms are especially suitable. Suitable carboxylic acid vinyl esters are vinyl acetate and vinyl propionate.
