In particular, flexible polymer materials are widely used in the medical field, as well as for packaging, extrusion coating and electrical wires and cables covering.

[0003] Often the recycled polyolefin composition especially recycled polypropylene composition and in particular that one derived from streams of post-consumer waste (PCW) has low MFR and poor elastic properties in terms of elongation at break. One way to increase the MFR of this kind of polypropylene compositions is to visbreak them by means of peroxides, however even if the melt flow rate of the composition is increased usually the elastic properties does not increase and sometimes they become worse.

[0009] The term "recycled" is used to designate polymer materials deriving from at least one cycle of processing into manufactured articles, as opposed to virgin polymers that is a polymer not subjected at least one cycle of processing into manufactured articles.

[0010] The term “consisting essentially of’, as used herein in connection with a polymer or polymer composition means that, in addition to those components which are mandatory, other components may also be present in the polymer or in the polymer composition, provided that the essential characteristics of the polymer or of the composition are not materially affected by their presence. According to the present disclosure, examples of components that, when present in customary amounts in a polymer or in a polymer composition, do not materially affect their characteristics are the catalyst residues, antistatic agents, melt stabilizers, light stabilizers, antioxidants, antiacids.

[0011] The features of the components forming the polypropylene composition are not inextricably linked to each other. This means that a certain level of preference of one the features should not necessarily involve the same level of preference of the remaining features of the same or different components. On the contrary, it is intended in the present disclosure that any component (A) to (D) and any preferred range of features of components (A) to (D) can be combined with any preferred range of one or more of the features of components (A) to (D) and with any possible additional component, and its features, described in the present disclosure.

[0012] Component (A) is a post consumer resin (PCR), in particular derived from post consumer beverage cartons and referred to as “Poly Al”, containing an amount of aluminum as above reported Component A) preferably comprises more than 50 wt% of polyethylene; for example polyethylene is a low density polyethylene (LDPE). (LDPE typically has a density of 900-940 kg / m3, for example 910-930 kg / m3. Due to the presence of aluminium, the density of component A is generally higher than the base polyethylene.). Component A preferably has an aluminium content preferably ranging from 0.5 to 15.0 wt%; more preferably from 1.0 to 8.0 wt%. Examples of component A) can be the EcoAllene® products sold by Ecoplasteam SpA, in particular EcoAllene AA00.

[0013] Component B) is a post consumer resin (PCR),. For example the products sold by “Vita plastics“ it is made mainly from polypropylene.

[0014] Component C) is an high melt flow rate homopolymer having narrow molecular weight distribution. For example commercial grade Metocene MF650Y sold by Lyondellbasell.

[0015] Preferably this homopolymer is prepared by using metallocene based catalyst. For example commercia grade Metocene MF650Y sold by Lyondellbasell.

[0016] Inorganic filler component D) are preferably selected form the group consisting of: calcium carbonate, barium sulphate, titanium dioxide and talc. Talc and calcium carbonate are preferred.

[0017] With the composition of the present invention it is possible to improve the elastic properties of recycled polymers in terms of elongation at break, and increase the MFR without the need to add huge amounts of virgin polymers and without the need to visbreak the composition. In fact, even if with the visbreaking process it is possible to increase the MFR of the composition, but the elastic properties are usually worsened so that it is not possible to use the recycled composition in the production of certain injection molded articles. Thus preferably the composition of the present invention is not visbroken

[0018] The whole polypropylene composition of the present disclosure can be obtained by mechanical blending of the components (A)-(D) according to conventional techniques.

[0019] The final composition comprising the components (A) - (D) may be added with conventional additives and pigments, commonly used in olefin polymers such as nucleating agents, extension oils and other organic and inorganic pigments.

[0020] The addition of inorganic fillers, such as talc, calcium carbonate and mineral fillers, brings about an improvement to some mechanical properties, such as flexural modulus and HDT. Talc can also have a nucleating effect.

[0021] The following examples are given in order to illustrate, but not limit the present disclosure.EXAMPLESCHARACTERIZATIONSXylene-soluble (XS) Fraction at 25 °C

[0022] 2.5 g of polymer and 250 ml of xylene are introduced in a glass flask equipped with a refrigerator and a magnetic stirrer. The temperature is raised in 30 minutes up to the boiling point of the solvent. The resulting clear solution is then kept under reflux and stirred for 30 minutes. The closed flask is then kept for 30 minutes in a bath of ice and water, then in a thermostatic water bath at 25 °C for 30 minutes. The resulting solid is filtered on quick filteringpaper. 100 ml of the filtered liquid is poured in a previously weighed aluminum container, which is heated on a heating plate under nitrogen flow to remove the solvent by evaporation. The container is then kept on an oven at 80 °C under vacuum until a constant weight is obtained. The weight percentage of polymer soluble in xylene at room temperature is then calculated.

[0023] The content of the xylene-soluble fraction is expressed as a percentage of the original 2.5 grams and then, by the difference (complementary to 100%), the xylene insoluble percentage (%).Melt Flow Rate (MFR)

[0024] Measured according to ISO 1133-1 at 230 °C with a load of 2.16 kg or 5 kg, as specified.Ethylene (C2) content

[0025] 13C NMR spectra were acquired on a Bruker AV-600 spectrometer equipped with cryoprobe, operating at 160.91 MHz in the Fourier transform mode at 120°C.

[0026] The peak of the Spp carbon (nomenclature according to “Monomer Sequence Distribution in Ethylene-Propylene Rubber Measured by 13C NMR. 3. Use of Reaction Probability Mode ” C. J. Carman, R. A. Harrington and C. E. Wilkes, Macromolecules, 1977, 10, 536) was used as internal reference at 29.9 ppm. The samples were dissolved in 1, 1,2,2- tetrachloroethane-d2 at 120°C with a 8 % wt / v concentration. Each spectrum was acquired with a 90° pulse, 15 seconds of delay between pulses and CPD to remove 1H-13C coupling. 512 transients were stored in 32K data points using a spectral window of 9000 Hz.

[0027] The assignments of the spectra, the evaluation of triad distribution and the composition were made according to Kakugo (“Carbon- 13 NMR determination of monomer sequence distribution in ethylene-propylene copolymers prepared with 5-titanium trichloridediethylaluminum chloride” M. Kakugo, Y. Naito, K. Mizunuma and T. Miyatake, Macromolecules, 1982, 15, 1150) using the following equations:PPP = 100 Tpp / S PPE = 100 Tps / S EPE = 100 Ts5 / SPEP = 100 Spp / S PEE= 100 Sp5 / S EEE = 100 (0.25 S s+0.5 S55) / SS = Tpp + Tpg + T55 + Spp + Sps + 0.25 Syg + 0.5 S55

[0028] The molar percentage of ethylene content was evaluated using the following equation:E% mol = 100 * [PEP+PEE+EEE]

[0029] The weight percentage of ethylene content was evaluated using the following equation: 100 * E% mol * MWEE% wt. = >E% mol * MWE + P% mol * MWp where P% mol is the molar percentage of propylene content, while MWE and MWp are the molecular weights of ethylene and propylene, respectively.

[0030] The product of reactivity ratio rm was calculated according to Carman (C. J.Carman, R.A. Harrington and C.E. Wilkes, Macromolecules, 1977; 10, 536) as:

[0031] The tacticity of Propylene sequences was calculated as mm content from the ratio of the PPP mmTpp (28.90-29.65 ppm) and the whole Tpp (29.80-28.37 ppm).

[0032] Ethylene C2 content of component b2 has been measured by measuring the C2 content on component B) and then calculated by using the formula C2tot=XblC2bl+Xb2C2b2 wherein Xbl and Xb2 are the amounts of components bl and b2 in the composition.FTTR Spectrum

[0033] The IR spectrum was determined by infrared (IR) spectroscopy by recording the sample against a background level of air with a Fourier transform infrared (FUR) spectrometer. The data acquisition parameters of the instrument were:■ purge time: 30 seconds minimum■ collection time: 3 minutes minimum■ apodization: Happ-Genzel■ resolution: 2 cm-1.

[0034] Sample preparation - Using a hydraulic press, a thick sheet was obtained by compression molding approximately 1 g sample between two sheets of aluminum foil. A small portion of the resulting sheet was cut to form a film. The film thickness was set to have a maximum absorbance of the CH 2 absorption band at -720 cm-1 of 1.3 au (% Transmittance > 5%). Molding conditions were performed at a temperature of approximately 180 ± 10°C (356°F) and a pressure of approximately 10 kg / cm2 (142.2 psi) for approximately one minute. After thepressure was released, the sample was removed from the press and cooled to room temperature. The spectrum of the pressed film was recorded as a function of absorbance versus wavenumbers (cm-1).Aluminium content
