| titleOfInvention | N-alkylbenzyl substituted polyethyleneimines |
| abstract | The invention comprises water-insoluble N-alkyl benzyl substituted polyethylene imines containing at least 1% of nitrogen and the use of these compounds, incorporated with hydrocarbon polymers, in order to render the resulting matrix polymer, containing from 0.1 to 1.5% nitrogen, by weight, dyeable by water-soluble anionic dyes. The N-alkyl substituted polyethylene imines are conveniently prepared, in a polar solvent, from alkyl benzyl halides, preferably the bromide, chloride or iodide, and a polyethylene-imine with a minimum M. Wht. of 10,000. Hydrocarbon polymers to which the invention is applicable include polypropylene, polyethylene, poly-1-butene, poly-(4-methyl-1-pentene), graft and block copolymers of two or more 1-alkenes or of non-terminal olefins with 1-alkenes, or mixtures of two or more of these copolymers. It is necessary to treat the mixture of hydrocarbon polymer and dye receptor polymer, in the physical form of filaments, yarns, fabrics, films, sheets &c., with an acidic reagent to render the matrix dye receptive; various acidic materials mentioned are mineral acids; acid anhydrides; acid gases; organo-carboxylic acids, both saturated and unsaturated, mono- and di-functional; halides which liberate hydrohalic acids with water; non-matallic halides and oxyhalides; metal halides; organic acid halides and organic halides where the halogen is on a carbon atom adjacent to an activating group, e.g. benzyl, allyl and compounds capable of complexing with basic nitrogen polymers.ALSO:Drawn or undrawn fibres, filaments, yarns and fabrics made from hydrocarbon polymers blended with a dye receptor polymer which is an N-alkylbenzyl substituted polyethyleneimine are dyed advantageously using water soluble anionic dyes. The hydrocarbon polymers must contain 0.5 to 10% of the N-alkyl benzyl polyethylene imine and are made highly dye-receptive by treating with an acidic reagent, the materials then being dyed in the conventional manner. This method of dyeing is suitable for polypropylene, polyethylene, poly-butene, poly (4-methyl-1-pentene) or mixtures thereof the alkyl benzyl substituted polyethyleneimines must be such that they contain at least 1% by weight of nitrogen and typical examples are where the alkyl variety contain from 6 to 20 carbon atoms. Suitable acidic reagents for treating the matrix polymer before dyeing include phosphorous pentachloride, sebacoyl chloride, hydrochloric acid, monochloroacetic acid and dichloracetic acid. Typical dyes include Capracyl Orange R, Alizann Sky Blue B, Reectone Red 2B, Pontamine Fast Yellow 4GL and Alizann Red 5. |
