Definitions
- the present invention relates to a polymer composition adapted for increasing the durability of goods contained in a sealed package, and to a method of producing said composition and to a method of use of said composition.
- a head-space which is filled with a gas which generally contains oxygen.
- the packages are filled with products which are susceptible to oxygen, i.e. which consist of or contain components able to react with oxygen changing the properties or the character of the product, it is important for the contents of the packages to be subjected to the oxygen present in said gas filled space to the least possible extent.
- the ratio between the volume of said head-space (and consequently the amount of oxygen) and the product is often relatively great.
- An object of the invention is to provide a composition which can be placed into operative association with the head-space of a sealed package so that the product contained in the package will not be. affected by the presence of oxygen in the head-space.
- the composition is effective to reduce or eliminate oxygen present in said head-space.
- the composition is placed in a permeable cover, such as a net, a bag or the like, which is included in the package.
- the composition is introduced in said gas filled space, i.e. as a rule said head space.
- the invention is based on the finding that certain metal complexes, especially of transition metals, have the capacity to bond with oxygen, and in this way eliminate molecular oxygen from said space, and in the utilization of this effect in connection with polymers.
- the polymers comprise thermoplastic resins and especially polyamides and copolyamides, the latter comprising copolymers of polyamides and other polymers.
- the polyamides can be aromatic and aliphatic, for example poly-m-xylylene-adipamide or nylon 6.6.
- a preferred group of polyamides are IIX nylons. These are polymers containing at last 70 mol% of structural units obtained from m-xylylenediamine alone or a xylylenediamine mixture containing m-xylylene-diamine and
- p-xylylenediamine in an amount of less than 30 % of the total amount and an ⁇ . ⁇ -aliphatic dicarboxylic acid having 6-10 carbon atoms.
- polystyrene resin examples include the homopolymers such as poly-m-xylylene adipamide, poly-m-xylylene scbacamide and
- poly-m-xylylene speramide copolymers such as m-xylylene/p-xylylene adipamide copolymer, m-xylylene/p-xylylene pyperamide copolymer and m-xylylene/p-xylylene azelamide copolymer, and copolymers of tiiese homopolymer or copolymer components and aliphatic diamines such as hexamethylenediamine, cyclic diamines such as piperazine, aromatic ciamines such as p-bis(2-aminoethyl)benzene, aromatic dicarboxylic acids such as terephthalic acid, lactams such as ⁇ -caprolactam, ⁇ -aminocarboxylic acids such as ⁇ -amino-heptoic acid and aromatic aminocarboxylic acids such as p-aminobenzoic acid.
- aliphatic diamines such as hex
- nylon 6 there may be incorporated polymers such as nylon 6, nylon 66, nylon 610 and nylon 11.
- the invention will be explained hereafter in connection with polyamides but it is not limited thereto.
- the effect of the polymer composition according to the invention i.e. its capacity to consume oxygen, is referred to as the "oxygen scavenger” effect or only the “scavenger” effect. It is theorized that a prerequisite for attaining this effect is the formation of an active metal complex, which is only possible if the polymer contains groups and/or atoms having the capacity to coordinate to the metal ion, and the polymer chain or chains are able to achieve a
- the metal complex has ligands originating from groups and/or atoms present in the polymer or formed therefrom.
- the effect of the active metal complex is irreversible in that the coordinating oxygen molecule is converted to highly oxidizing ions, for example, ions of superoxide or peroxide, which react further in the "organic" plastic phase in which they are present.
- polyamides or copolyamides are used together with at least one of the following metal ions; cobalt, nickel, iron, the palladium metals, i.e.
- ruthenium, rodium, palladium the platinum metals, i.e. osmium, iridium, platinum; copper or manganese.
- iron and cobalt are preferred, and cobalt is most preferred.
- composition of the invention can be present in the composition of the invention, which are conventional and do not substantially interfere with the scavenging effect.
- examples of such components are drying agents, anti-clogging agents, dyes, diluents, fillers etc.
- the composition is present in the form of particles, such as granules and pellets. Pellets normally as spheres or small cylinders are most preferred, mainly due to their durability.
- the size of the particles is not critical but for effective results it is preferably in the range of 0.001-0.05 cm 3 .
- the amount of particles in relation to the volume of the head space is a function of the susceptibility of the goods to oxygen degradation and, in general, the volume of particles present in the head space should be between 1 and 50 per cent of the head space volume exclusive of the composition.
- a further object of the invention is to provide a method of producing the polymer composition.
- the method comprises treating the polymer, preferably in particulate form, with a metal compound, in dissolved or slurry state in a volatile solvent
- the volatile solvent composition can be a single solvent or a mixture of solvents all of which need not be volatile.
- the solvent is etha ⁇ ol, preferably 96 % ethanol.
- the polymer which preferably is granulated or pelleted, is refluxed with the metal compound dissolved or suspended in slurry state in the volatile composition for a sufficient time period to form the active oxygen consuming (scavenging) component of the composition.
- the length of the time period, during which refluxing takes place, is readily determined by one skilled in the art in each case and is not critical according to the invention.
- the metal compound comprises a salt, preferably a halide, and particularly a chloride, of the above discussed metals, and especially iron. cobalt and nickel.
- a salt preferably a halide, and particularly a chloride
- iron. cobalt and nickel These metals, i.e. iron, cobalt and nickel, the palladium metals and the platinum metals are designated as transition metals belonging to series 1, 2 and 3 in the Periodic Table.
- the choice of the appropriate salt depends on its solubility in the solvent composition in that the time that it takes to prepare the active component is proportionately reduced in relation to higher solubility of the metal salt.
- the anion of the metal compound can be inorganic, for example, a chloride, or organic, for example an acetate or stearate.
- Example 1 The procedure of Example 1 was repeated but instead of nylon 6.6 poly-m-xylylene-adipamide was used (a polymer manufactured and sold by Mitsubishi Gas Chemical Co., Japan under the designation "MXD6").
- MXD6 Mitsubishi Gas Chemical Co., Japan under the designation
- the cobalt content of the dried pellets obtained amounted to 4500 ppm (mean value).
- example 2 The procedure of example 2 was repeated but with the metal compounds iron chloride and nickel chloride respectively in solution at a concentration of 0.24 g/ml.
- the polymer was "MXD6". By varying the amount of solution in relation to the amount of polyamide, pellets were prepared having various metal contents.
- example 1 The procedure of example 1 was repeated but various salts of metals belonging to the palladium group and the platinum group were used, i.e. ruthenium, rodium and palladium and osmium, iridium and platinum, respectively.
- Pellets comprising nylon 6.6 containing 7000 ppm cobalt prepared in accordance with example 1 and pellets comprising poly-m-xylylene- adipamide containing 4500 ppm cobalt prepared in accordance with example 2 were packed in metal cans (40 g/68 ml can) which were sealed by means of double-seamed metal lids.
- the size of the pellets was 0.01-0.02 cm 3 and the volume of the head-space was 33-35 cm 3 .
- Samples were taken from the head-space (one sample per can) immediately after the filling, after two weeks and after 4 weeks for gas chromatographic determination of the oxygen content. The results appear from table I.
