Title: Olefinic hydrocarbon polymer compositions
IPC: C08L29/14
Filed: 1962-05-14
Abstract: A dyeable polymer composition comprises a crystallizable olefinic hydrocarbon polymer, a carboxylic acid salt or chelate compound of nickel, cobalt, chromium, titanium, zirconium or mixed rare earth metals and a polymeric modifier selected from polyvinyl acetal, a homo- or copolymer of <FORM:1007337/C3/1> (where R is hydrogen or methyl and R1 is alkyl, alkoxyalkyl, cycloalkyl, aralkyl, alkaryl or aryl) or a vinyl pyridine, or a copolymer of an N-substituted acrylamide, vinyl acetate, ethyl fumarate or styrene.  The olefinic hydrocarbon polymer may be a polymer of styrene, ethylene, propylene, butylene, 4-methyl-1-pentene or allyl benzene and the polymer may be in the form of a fibre, film or other shaped object. Preferably the metal chelate compound or carboxylic acid salt of the metal is incorporated into the polymeric modifier by rolling in a rubber mill or blending in a Banbury mixer. The resulting salt-containing modifier is then incorporated into the olefinic hydrocarbon polymer by mechanical blending followed by melt extrusion.  In the examples crystalline polypropylene is the crystallizable olefinic hydrocarbon polymer employed.  Cobaltous acetate tetrahydrate, nickel perlargonate, nickel stearate, nickel hexanoate perlargonate, cobalt perlargonate, cobalt tartrate, nickel adipate, the nickel chelate derivatives of 2,21-thiobis (4-t.-octyl-phenol), nickel acetate, cobalt 2-ethylhexanoate and chromic acid are the carboxylic acid salts or chelate compounds employed.  Poly-(vinylbutyral), poly-(methyl-methacrylate), a methyl methacrylate/ethyl fumarate copolymer, poly - (n - butylmethacrylate), a methylmethacrylate/vinyl acetate copolymer, a methylmethacrylate(styrene copolymer, a methylmethacrylate/N,N-dimethylacrylamide copolymer, poly-(2-methyl-5-vinyl-pyridine) and an N-methylmethacrylamide/styrene copolymer are the polymeric modifiers employed in the examples.  Specifications 716,564, 931,920, 968,389, 968,692 and 975,701 are referred to.ALSO:A polymer composition comprising a crystallizable olefinic hydrocarbon polymer, a carboxylic acid salt or chelate compound of nickel, cobalt, chromium, titanium, zirconium or mixed rare earth metals and a polymeric modifier which is a polyvinyl acetal, a homo- or copolymer of a vinyl pyridine or a monomer <FORM:1007337/D1-D2/1> where R is hydrogen or methyl and R1 is alkyl, alkoxyalkyl, cylcoalkyl, aralkyl, alkaryl or aryl, or a copolymer of an N-substituted acrylamide, vinyl acetate, ethyl fumarate or styrene, is dyed or printed with a dyestuff capable of undergoing chelation.  The polymer composition to be dyed may be in the form of fibres, yarns, films or shaped objects.  Suitable dyes are a -hydrokyanthraquinone compounds, ortho-hydroxyazo compounds and compounds having the formula <FORM:1007337/D1-D2/2> where A is a monocyclic benzene nucleus containing a <FORM:1007337/D1-D2/3> group where R is hydrogen, methyl or ethyl.  In the examples the crystallizable olefinic hydrocarbon polymer is polypropylene and the dyes employed are 2-(4-acetamidophenylazo)-4-methyl phenol; 4-hydroxy-1-methyl-3-(m-nitrophenylazo)-carbostyril and 1-(4-hydroxyethylanilino)-4, 5-dihydroxy-8-nitroanthraquinone. Other dyes mentioned are 1-amino-4, 5-dihydroxy-2-methoxyanthraquinone and 1-(2-hydroxy-5-sulphonamidophenylazo)-2-hydroxynaphthalene. Specifications 716,564, 931,920, 968,389, 968,692 and 975,701 are referred to.
