Title: Improvements in or relating to the stabilisation of naphthol-rubber products
IPC: C09J7/38
Filed: 1943-01-13
Abstract: Naphthol-rubber products produced as described in Specification 520,985, [Group V], are stabilised as regards discoloration by light and heat by mixing them with amino-nitrogen containing polymers capable of being formed into films and soluble in organic solvents and in 2 per cent acetic acid.  The mixture with the addition of rubber, paraffin and fatty waxes, gums, natural resins (rosin), hydrogenated rosin, ester gums, indene resins, alkyd resins, damar, plasticisers, e.g. phthalates, phosphates, chlorinated paraffin, dixylyl ethane, chlorinated diphenyls, hydrogenated methyl abietate, di-ethyl-toluene-sulphonamide, camphor, hydrocarbon oils and solvents, e.g. toluene, benzene ethylene dichloride, acetone, dimethyl formamide, tetrachlorethane, kerosene; wetting agents, e.g. alkyl sulphates, may be used as cements, adhesives, moisture-proof coating agents for films of cellulose and cellulose derivatives and for laminating and joining sheets of metal, cardboard, cloth, "Scotch tape."  The amino nitrogen containing polymers comprise: (1) reaction products of phenols, amino phenols, phenol-lignins with aldehydes, amines, ammonia and piperazine; (2) reaction products of diaryl guanidines, ureas with formaldehyde and amines; dimethylol urea dimethyl ether and amines; (3) reaction products of amino alcohol esters with polycarboxylic acids; (4) polymers of amino alcohol esters of acrylic acid; reaction products of vinyl-ketone polymers and amines and ammonia; of polyvinyl chloracetate and secondary aliphatic amines; (5) reaction products of ketones, formaldehyde and amines or ammonia; (6) aromatic amine aldehyde resins; (7) polymers of epichlorhydrin and amines in presence of stannic chloride; (8) products obtained by the stannic chloride; (8) products obtained by the catalytic hydrogenation of resins having ketone groups in the presence of amines or ammonia; (9) reaction products of protein, aldehydes or ketones and amines. Specifications 283,109, [Class 2 (ii)], 284,589, [Class 2 (iii)], 342,325, 438,523, 475,131, and U.S.A.
