Definitions
- the invention relates to a molding composition composed of an olefin polymer, in particular a propylene polymer, containing 5-50% by weight glass fibers which are bonded to the olefin polymer by means of a compatibilizer, and from 10 "4 to 1 % by weight of a phthalocyanine pigment as the nucleating agent.
- EP 663 418 A1 describes, for example, a polypropylene molding composition which is reinforced with glass fibers.
- compatibilizers or coupling agents which ensure good binding of the glass fibers to the polyolefin matrix.
- the compatibilizers frequently comprise firstly a reactively modified polymer which is compatible with the matrix polymer as a coupler, and secondly a compound having reactive polar groups which can bond both to the glass fibers and to the coupler.
- nucleation it is likewise generally customary to nucleate unreinforced polymers of propylene to improve the stiffness and strength, but also the transparency, of the molding produced therefrom.
- phthalocyanine pigments are also used as nucleating agents. The nucleation generally leads to an improvement in the tensile strength and stiffness, but not to a significant improvement in the impact strengths, and often to a reduced yield elongation and tensile strain at break.
- a particular disadvantage of nucleating agents such as sodium benzoate is the only moderate hot water resistance and vapor resistance of the polyolefin molding compositions, especially in the case of long-term contact over several weeks or months. It is an object of the present invention to provide a polyolefin molding composition which exhibits improved matrix binding of the glass fibers and therefore better mechanical properties and is obtainable inexpensively and has improved resistance to hot water, especially in the presence of detergents.
- the molding compositions according to the invention comprise an olefin polymer containing 5-50% by weight of glass fibers and from 10 "4 to 1% by weight, preferably from 10 "3 to 10 "1 % by weight, of a phthalocyanine pigment as a nucleating agent.
- a phthalocyanine pigment as a nucleating agent.
- Essential for the polyolefin molding composition according to the invention is firstly the content of from 5 to 50% by weight of glass fibers based on the overall composition.
- the glass fibers may be either cut glass fibers having a length of from 3 to 6 mm or long glass fibers, although preference is given to using cut glass fibers. Preference is further given to using from 10 to 40% by weight, more preferably from 20 to 40% by weight, of glass fibers.
- cut glass fibers also known as chopped strands.
- the glass fibers used preferably have a length of from 3 to 6 mm, more preferably from 3 to 4.5 mm, and a diameter of from 10 to 20 ⁇ m, preferably from 12 to 14 ⁇ m.
- the length of the glass fibers in the molding composition is from 50 ⁇ m to 3 000 ⁇ m, preferably from 50 to 1 000 ⁇ m.
- a polar-functionalized compatibilizer is used.
- One type which can be used is low molecular weight compounds which serve exclusively to make the glass fibers less hydrophilic and therefore more compatible with the polymer. Suitable compounds are, for example, silanes such as aminosilanes, epoxysilanes, amidosilanes or acrylosilanes.
- the compatibilizers preferably comprise a functionalized polymer and a low molecular weight compound having reactive polar groups.
- the functionalized polymer is preferably graft or block copolymers which are compatible with the matrix polymer.
- a propylene homopolymer as the matrix component preference is given, for example, to using a graft or block copolymer of propylene as the functionalized polymer.
- the low molecular weight compound serves to couple the glass fiber to the functionalized polymer and thus to bind it securely to the polyolefin matrix.
- the low molecular weight compound used is preferably an amino- or epoxysilane, more preferably an aminosilane.
- the aminosilanes bond with the silane hydroxyl groups to the glass fiber, while the amino groups form a stable amide bond, for example with polypropylene grafted with maleic anhydride.
- the compatibilizers can be used preprepared or prepared in situ. It is particularly advantageous to apply the low molecular weight component to the glass fibers before it is incorporated into the polyolefin matrix.
- the functionalized polymer can be generated in situ in a simple manner by reactive extrusion of the matrix polymer, for example with maleic anhydride. It is also possible to use a masterbatch which comprises the glass fibers and the compatibilizer in premixed form.
- the glass fiber-reinforced polypropylene molding composition is nucleated with a phthalocyanine pigment.
- the phthalocyanine pigments themselves are well known and are derived from the basic phthalocyanine structure by incorporating a central metal ion and by substituting the phthalocyanine ring. In practice, the central atoms used in the pigments are copper, nickel and cobalt, and copper is the preferred central atom.
- the basic phthalocyanine structure may optionally be substituted, in particular with chlorine or bromine atoms. Substitution with organic radicals can also be carried out to adapt the nucleation properties.
- Suitable phthalocyanine pigments are, for example, unsubstituted copper- phthalocyanine (phthalocyanine blue), polychlorinated copper-phthalocyanine (phthalocyanine green, C 32 H 2 N 8 CI 14 Cu), cobalt-phthalocyanine (C 32 H 16 N 8 Co), nickel-phthalocyanine (C 32 H 16 N 8 Ni). Particular preference is given to unsubstituted copper-phthalocyanine.
- Unsubstituted copper-phthalocyanine and polychlorinated copper-phthalocyanine are sold, for example, by Clariant, Frankfurt, DE under the names PV Echtblau and PV Echtgr ⁇ n respectively.
- the proportion of nucleating agent is between 10 "4 and 1% by weight, based on the overall composition. Preference is given to using from 10 "3 to 10 "1 % by weight, particular preference to from 5-10 "3 to 5-10 "2 % by weight, of the nucleating agent.
- the combination of glass fiber reinforcement and nucleation with phthalocyanine pigments results in a molding composition which is improved over the prior art with regard to the stiffness and toughness.
- the adhesion of the glass fibers to the polymer matrix is surprisingly distinctly improved with the same compatibilizer, which results in an improvement in the propagation of cracks in the molding composition.
- the nucleation with phthalocyanine pigments surprisingly results in distinctly improved long-term stabilities in the tensile strengths and impact strengths in hot water and hot detergents, for example over testing times of 1 000 hours at 95°C, compared to nonnucleated glass fiber-reinforced comparative specimens.
- Advantages in the long-term stability of the inventive molding compositions can also be recognized, for example, in the long-term tests in aqueous detergents in accordance with the UL standards 2157 and 749, testing over 138 days at 82°C.
- the particular advantage of the phthalocyanine pigment is that it is substantially compatible with the customary compatibilizers, i.e. there is no or hardly any mutual interference between the action of nucleating agent and compatibilizer.
- the molding compositions according to the invention are obtainable by melting and mixing the olefin polymer with the phthalocyanine pigments and the glass fibers, and the mixing is effected in a mixing apparatus at temperatures of from 180 to 320°C, preferably from 200 to 280°C, more preferably from 220 to 260°C.
- Useful mixing apparatus in this context is in particular extruders or kneaders, and particular preference is given to twin-screw extruders.
- the olefin polymer may be mixed with the nucleating agent and the glass fibers in one step or else in a plurality of steps. Preference is given to initially melting the olefin polymer with the nucleating agent and further additives in the mixing apparatus, and to mixing them, and subsequently mixing the glass fibers with the melt, in order to reduce the abrasion in the mixing apparatus and the fiber breakage.
- Useful matrix components of the molding composition according to the invention are homopolymers and copolymers of alpha-olefins having from 2 to 12 carbon atoms, for example of ethylene, propene, 1-butene, 1-hexene or 1-octene. Also suitable are copolymers and terpolymers which, in addition to these monomers, contain further monomers, in particular dienes, for example ethylidenenorbornene, cyclopentadiene or butadiene.
- Preferred matrix components are polyethylene, polypropylene, polybutylene and/or copolymers of ethene with propene, 1-butene, 1-hexene or 1-octene.
- any commercially available type thereof can be used.

- Such polyolefins may also contain an impact strength component, for example EPM or EPDM rubber, or SEBS.
- the comonomer content of the ethylene copolymer should not exceed 1 mol% of the total amount of monomers used.
- Preferred comonomers are 1-olefins, and particularly preferred comonomers are 1-butene, 4-methyl-1- pentene, 1-hexene and 1-octene.
- the polyethylene may also be a blend of two or more polyethylene components.
- the propylene polymer used may in particular be a propylene homopolymer or else a propylene copolymer having up to 30% by weight of other olefins having up to 10 carbon atoms in copolymerized form.
- Such other olefins are in particular C 2 -C 10 -1-alkenes such as ethylene, 1-butene, 1-pentene, 1-hexene, 1-heptene or 1-octene, and preference is given to using ethylene, 1-butene or ethylene and 1-butene.

- the copolymers of propylene have a random structure, they generally contain up to 15% by weight, preferably up to 6% by weight, more preferably up to 2% by weight, of other olefins having up to 10 carbon atoms, in particular ethylene, 1-butene or a mixture of ethylene and 1-butene, as comonomers.
- the block or impact copolymers of propylene are polymers in which, in the first stage, a propylene homopolymer or a random copolymer of propylene having up to 15% by weight, preferably up to 6% by weight, more preferably up to 2% by weight, of other olefins having up to 10 carbon atoms as comonomers is prepared and then, in the second stage, a propylene-ethylene copolymer having ethylene contents of from 15 to 99% by weight, the propylene-ethylene copolymer additionally being able to contain further C -C ⁇ 0 -olefins, is polymerized thereto.
- the random copolymers of propylene are polymers in which, in the first stage, a propylene homopolymer or a random copolymer of propylene having up to 15% by weight, preferably up to 6% by weight, more preferably up to 2% by weight, of other olefins having up to 10 carbon atoms as comonomers is prepared and then, in the second stage, a propylene homopolymer or a random copolymer of propylene having up to 15% by weight, preferably up to 6% by weight (more preferably up to 2% of comonomers) of other olefins having up to 10 carbon atoms is polymerized thereto.
- the polymers of the two stages differ in the molar mass and the comonomer content.
- the ethylene content of the blend is 15% by weight or preferably up to 6% by weight and more preferably up to 3% by weight, of comonomers.
- the polyolefin generally has an MFR (230°C/2.16 kg) of from 0.2 to 200 g/10 min to ISO 1133, preferably between 0.5 and 100 g/10 min and more preferably between 2 and 30 g/10 min.
- Preference is further given to polypropylene molding compositions having a monomodal molar mass distribution.
- the molding compositions according to the invention may also comprise customary additives and auxiliaries, for example stabilizers against damaging processing effects, antioxidants against heat oxidation and aging, UV action, neutralizing agents, fillers, organic and inorganic pigments or pigment preparations, for example carbon black dispersions in polyolefins, antistats, nonpolar waxes or specific low molecular weight glidants and lubricants.
- UV stabilizers especially monomeric and oligomeric HALS, antistats and polar waxes and also stearates are less suitable for the inventive molding compositions, or, if at all, in very low concentrations, since they may likewise react with the coupler of the compatibilizer and thus reduce the efficiency of the coupling.
- the amount of additives and auxiliaries should not exceed 10% by weight based on the total amount of the material, preferably 5% by weight.
- the olefin polymers used in the molding compositions according to the invention can be obtained with all common processes and catalysts.

- the customary reactors used for the polymerization of C 2 -C 10 - olefins can be used.
- Suitable reactors include continuous horizontal or vertical stirred tanks, circulation reactors, loop reactors, stage reactors or fluidized bed reactors.
- the size of the reactors is of no great importance for the preparation of the molding compositions according to the invention. It depends on the output which is to be achieved in the individual reaction zone or zones.

Moldings produced from the molding composition according to the invention are suitable, as a result of their improved stiffness and toughness even when cut glass fibers are used, for applications which have hitherto been reserved for long fiber-reinforced propylene polymers.
- the molding composition according to the invention also features very good durability toward hot water and detergents. They can therefore be used particularly advantageously as the material for moldings which are exposed to contact with hot water, wash and rinse liquors and other aggressive materials.
- the present invention therefore further provides the use of the molding composition according to the invention as a wash liquor vessel (preferably not visible) in washing machines, and also wash liquor vessels produced from the molding composition according to the invention, but also the use for water and liquor pump casings.
