Abstract:
A new class of basic polyamides having a molecular weight between about 2,000 and 200,000. The polyamides are prepared by first reacting an acrylic or methacrylic ester with a monoamine and then further reacting the product obtainable with a polyamine. The polyamides are suitable for use as tinctorial modifiers for polymeric materials and particularly for crystalline polyolefins consisting essentially of isotactic macromolecules.

Abstract:
Shaped articles comprise a mixture of a crystalline olefin polymer and 1 to 25 per cent based on the weight of olefin polymer of a basic nitrogen containing polycondensate of epichlorohydrin with a bis-secondary amine and a diphenolic compound. The articles may be textile fibres and filaments, tapes or films. The olefin polymer may be polypropylene. The polycondensate may be prepared from dialkyl alkylenediamines, piperazine, 2-methyl piperazine or 2,5-dimethyl piperazine and 2,2-bis(4-hydroxyphenyl)propane, pyrocatechol, resorcinol, hydroquinone or 4,41-dihydroxy diphenyl methane. The polycondensates may be rendered water-insoluble by treating the articles with epoxy compounds, isocyanates, aldehydes, halogens or divinyl benzene. The polycondensates are said to improve the dyeability of the olefin polymer articles, which may be further improved by treatment with an acid. In examples epichlorohydrin and piperazine are reacted with (1 and 2) bisphenol A and (3) hydroquinone in methanol with the addition of sodium hydroxide in the later stages of the reaction. The products are mixed with polypropylene, calcium stearate and titanium dioxide and the resulting compositions melt spun into fibres which are stretched, treated with a solution of ethylene glycol diglycidyl ether and dyed.ALSO:Articles such as fibres, filaments, films and tapes made of compositions comprising a crystalline olefin polymer and 1 to 25 weight per cent based on said polymer of a polycondensate of epichlorohydrin, a bis secondary amine and a diphenolic compound or diglycigyl ether thereof, may be dyed with acid, metallised and dispersed dyestuffs. The olefin polymer may be polypropylene and the polycondensate may be derived from dialkyl alkylenediamines, piperazine, 2-methyl piperazine or 2, 5-dimethyl piperazine and 2,2-bis(4-hydroxyphenyl) propane, pyrocatechol, resorcinol, hydroquinone or 4,4\sv-dihydroxy diphenyl methane. The polycondensates may be rendered water-insoluble by treating the articles with epoxy compounds, isocyanates, aldehydes, halogens or divinyl benzene, and dyeability may be further improved by treating the articles with an acid. Dyeing with acid and metallised dyestuffs may be effected in the presence of ammonium acetate and a surface active agent, e.g. an alkyl phenol/ethylene oxide condensate, with the addition of acetic acid to improve exhaustion of the dyebath. Dyeing with disperse dyestuffs may be effected in the presence of a surface active agent. In examples fibres made of compositions comprising polypropylene, calcium stearate, titanium dioxide and polycondensates of epichlorohydrin, piperazine and (1 and 2) bisphenol A and (3) hydroquinone are dyed with acid, metallised and disperse dyes.
Abstract:
There are disclosed dyeable fibers comprising mixtures of olefinic polymers with terpolymers of (a) vinyl or isopropenyl derivatives of aromatic hydrocarbons, such as styrene, vinyltoluene, alpha-methylstyrene and the like; (b) alpha, betaunsaturated nitriles, such as acrylonitrile, methacrylonitrile, and the like; and (c) aromatic and cycloaliphatic hydrocarbons, containing a double vinylenic bond, such as indene, acenanaphthylene, cyclohexene, and the like. The olefin polymer may be, and preferably is, a high molecular weight polypropylene consisting essentially of isotactic polypropylene made up of isotactic macromolecules, i.e., of macromolecules having substantially isotactic structure and being non-extractable with boiling n-heptane. A process for preparing the dye-receptive fibers is also disclosed.

[Also in Division D1] A basic nitrogen-containing polycondensate useful as an additive to polyolefins and other polymers comprises the reaction product of epichlorohydrin and a seven-membered heterocyclic bi-secondary diamine, which product has been modified with a polyamine containing one or more primary amino groups. Suitable seven-member heterocyclic bi-secondary diamines have the general formula wherein R represents H or an alkyl group which may be the same or different in each case. Examples are 5,5,7-trimethylpiperazine, 5,6,7- trimethylpiperazine, 5,7 - dimethylpiperazine, 5,6 - dimethyl - 7 - propylpiperazine and tetramethylpiperazine. Suitable polyamines include hexamethylene diamine, ethylene diamine, diethylene triamine, tetraethylenepentamine and aminoethylpiperazine. The molar ratios of epichlorohydrin/heterocyclic amine/polyamine are generally 1 : 0À5-0À99 : 0À01-1 respectively. 1-25 % of the modified polycondensates may be incorporated into polyolefin compounds having isotactic structures and prepared from monomers of the general formula RCH = CH 2 where R is hydrogen or an alkyl or aryl group, such as polyethylene, polypropylene, polybutene-1, polypentene-1, polyhexene-1, poly-4- methyl-pentene-1, polyoctene-l or polystyrene, in order to improve dyeability of their fibres (see Division D1). Other polymers mentioned are those of acrylonitrile and vinyl chloride. The mixing may be carried out in the presence of a dispersing agent and the mixture granulated before extruding. The filaments may be insolubilized by reacting with epoxides, isocyanates, aldehydes, halogens or metal salts. Specification 1,104,059 is referred to.
