Definitions
- This invention relates to polyketone polymers. More particularly, the invention relates to a reinforced flame retardant polyketone polymer blend.
- High molecular weight linear alternating polyketones are of considerable interest because they exhibit a good overall set of physical properties.
- This class of polymers is disclosed in numerous patent documents, for example in US-A-4880865 and US-A-4818811.
- the linear alternating polyketones have established utility as premium thermoplastics in the production of shaped articles such as containers for food and drink and parts for the automotive industry. These articles can be produced by processing the polyketone polymer according to well known methods.
- Certain mechanical properties of the polyketones can be improved through blending with e.g. reinforcements or other polymers, or by the addition of additives to the material.
- the stiffness and heat resistance of polyketones are improved by the addition of a reinforcement to the material, such as glass fibres.
- the rise of the electronics industry has placed a premium on the development of polymers which can be used to support electrical circuitry.
- the polymers so used should not be unfavourably affected by their proximity to changing electrical fields and currents nor should their intrinsic properties unfavourably affect the circuitry about which the polymer is exposed. This can be best expressed by considering a simple electrical circuit such as the emplacement of two electrical conductors supported on a polymer support which maintains them at some finite separation. A potential difference is found between the two conductors. In such a case, among other desirable features of the material, the polymer must physically retain the separation of the two conductors to avoid a short circuit.
- Exposing the polymer to a non-sterile environment subjects it to the deposition of any number of materials on its surface. As these materials become affixed to the surface of the polymer they cause a decrease in surface resistance. This enables a current to flow and thereby generates heat at the point about the deposition. Some areas may have considerably more deposits than others which can lead to voltage gradients which ultimately results in surface discharges . Such surface discharges produce very high temperatures at the point at which they occur and thereby erode the surface. This erosive action is called tracking.
- CTI Comparative Tracking Index
- Flammability is another important consideration in applying particular polymers in electrical or electronic uses. Many polymers and polymer blends must be modified by the addition of a flame retardant to attain the desired level of resistance to flammability.
- a flame retardant for example, US-A-4761449 proposes the addition of an alkaline earth metal carbonate to polyketone to form a flame retardant blend.
- US-A-4885328 proposes the use of magnesium hydroxide as the flame retardant for poly- ketones.
- US-A-4921897 proposes the addition of zinc borate or barium borate as flame retardants for poly ⁇ ketones.
- a combination of additives to a polymer does not necessarily uniformly improve the properties of the polymer.
- neat poly ⁇ ketones, reinforced polyketones and flame retarded polyketones possess CTIs of 600V. This is generally considered to be superior performance.
- polyketones, reinforcement, and flame retardant when polyketones, reinforcement, and flame retardant are combined the material exhibits an unsatisfactorily low CTI, for example as low as 250V.
- the addition of other additives such as pigments also brings some uncertainty into the overall set of physical properties that the polymer will ultimately display. Reinforced flame retarded polyketones having CTIs in the range found useful for electrical end uses would greatly contribute to the range of applications for such polymer blends.
- Such polyketone blends would be especially beneficial if they could obviate or reduce the need for one or more other additives such as pigments.
- Such materials are useful in electrical connectors and switch gears, as supporting materials and fasteners for electrical circuitry, and as insulation for wires among other applications.
- CTI improving compounds for use in the invention are zinc compounds, which are known per se to act as flame retardant in polyketones, and that other CTI improving compounds are silicon oils.
- the zinc compounds are also effective pigments for the reinforced flame retardant polyketone polymers.
- the present invention relates to a reinforced flame retardant polyketone polymer blend comprising a polyketone polymer, a reinforcement, a flame retardant other than a zinc compound, and a comparative tracking index (CTI) improving compound selected from zinc compounds and silicon oils.
- CTI comparative tracking index
- the invention relates also to a method for improving the CTI of a reinforced flame retardant polyketone, comprising admixing the polyketone with a reinforcement, a flame retardant other than a zinc compound, and a CTI improving compound selected from zinc compounds and silicon oils.
- the present invention also relates to a reinforced flame retardant polyketone polymer blend having a CTI greater than 375 V, as measured by ASTM D 3638-93, preferably greater than 400 V.
- the terminology "reinforced flame retardant blend” is used to indicate that the blend comprises a reinforcement and a flame retardant.
- the blends according to the invention have in particular a flame retardancy of at least V-l, more in particular at least V-0, as measured by the UL 94

Preferably, there will be from 10 units to 100 units incorporating a moiety of ethene for each unit incorporating a moiety of the other ethylenically unsaturated compound(s) .
- the polymer chain of preferred polyketone polymers is therefore represented by the repeating formula
- G is the moiety of the ethylenically unsaturated compound of at least 3 carbon atoms polymerized through the ethylenic unsaturation and the ratio of y.x is typically no more than 0.5.

- alkaline earth metal hydroxide or carbonate which represents a preferred class of flame retardants, is meant a hydroxide or carbonate of a metal of group IIA of the Periodic Table of Elements. While hydroxides of beryllium, magnesium, calcium, strontium, and barium are suitable, the preferred alkaline earth metal hydroxide component is magnesium hydroxide. Most preferred is magnesium hydroxide. Preferred alkaline earth metal carbonates are calcium carbonate and partially hydrated magnesium calcium carbonate. Most preferred is partially hydrated magnesium calcium carbonate.
- the quantity of the flame retardant compound is suitably selected between 10 and 70 %w, more suitably between 20 and 55 %w, in particular between 25 and 40 %w, based on the weight of the blend.
- the CTI improving compound may be selected from zinc compounds and silicon oils.

- a CTI improving compound is combined with a flame retardant, in particular an alkaline earth metal hydroxide, it may occur that there is a small decrease in the level of the flame retardancy of the blend. This is more in particular the case when a hydrated zinc borate is used as the CTI improving compound. It has unexpectedly been found that the decrease in flame retardancy is smaller or not noticeable at all when as the CTI improving compound a silicon oil or a sub ⁇ stantially anhydrous zinc borate is used. Therefore there is a preference for using a silicon oil or a substantially anhydrous zinc borate as the CTI improving compound.

- the blends of this invention are produced by mixing the various materials with the polyketone polymer.
- the method by which this achieved is not critical to this invention.
- Good dispersion of the flame retardant generally contributes to good flame retardancy and CTI performance.
- the components are dry blended in particulate form and converted to a substantially uniform composition, e.g., by extrusion.
- the polyketone polymer is heated until molten and the other components are mixed throughout the polymer by use of, e.g., a high-shear mixer or extruder. Reinforced flame retardant polyketone polymer blends have frequently a pronounced colour.
- inventive blends can be processed by conventional methods such as extrusion and injection moulding into various articles of manufacture such as electrical connectors and switch gears, as supporting materials and fasteners for electrical circuitry, and as insulation for wires among other applications.

- This example illustrates the substantial improvement in the CTI of blends made according to this invention (having both a zinc borate and alkaline earth metal hydroxide or carbonate) relative to blends without the zinc borate.
- Standard test method ASTM D 2863-77 was used to evaluate the burning behaviour of the blends of example 2. This test measures the minimum concentration of oxygen in an oxygen-nitrogen atmosphere that is necessary to initiate and support a flame for 180 seconds on a test specimen. The result of the test is expressed as the percentage of oxygen in the oxygen-nitrogen atmosphere and is called the Limiting Oxygen Index (LOI) of the composition. LOIs are reported in Table 1 below.
- a linear terpolymer of carbon monoxide, ethene and propene was produced by polymerizing the monomers in the presence of a catalyst formed from palladium acetate, the anion of trifluoroacetic acid and 1, 3-bis [bis (2-methoxy ⁇ phenyl)phosphino]propane.
