Definitions

  • Opaque plastics materials find considerable use in applications which require a resistance to scratches and scuffs.
  • car manufacturers utilise coloured plastics materials (typically polypropylene) for the interior trim of their vehicles.
  • the interior trim of a car is subjected to considerable scratching and scuffing.
  • a plastics material which may be pigmented as desired but is able to resist the scratches and scuffs of everyday use.
  • scratch resistance is required in opaque materials.
  • an opaque polymer composition comprising a blend of: a matrix polymer selected from the group consisting of polypropylene, high density polyethylene and poly- 4-methylpentene -1; at least one impact modifier wherein said impact modifier is a copolymer or terpolymer of ethylene and at least one other ⁇ -olefin or diolefin; at least one opacifier selected from the group consisting of colourants and fillers and combinations thereof; and at least one block copolymer of at least one styrenic monomer and at least one olefinic or diolefinic monomer.
  • isotactic polypropylene typically comprises approximately 3% atactic polypropylene. It is preferred that the amount of atactic polypropylene is less than 8%.
  • the random copolymer of ethylene and propylene may be manufactured by introducing the ethylene monomer into the copolymer in a mixed feed with propylene. This generates random statistical ethylene-propylene copolymer (EP copolymer) chains.
  • the overall proportion of ethylene units in the random copolymer used in the invention is typically from 3 to 15, more usually 5 to 12 and especially about 6 (for example 5 to 7), mole % based on total monomer. The remainder of the units are derived from propylene although a small proportion of other olefin monomers can be included, for example up to 10% by weight of the propylene units of C 4 to C 10 alpha olefin monomers.
  • the matrix polymer may also contain effective amounts of additional polymers such as nylon 6, nylon 66 and polyphenylene oxide.
  • the impact modifier, the polymer of ethylene and ⁇ - olefin typically has a density in the range from 860 to 930 kg/m 3 , preferably 890 to 920 kg/m 3 .
  • the melt flow index ASTM D1238 CONDITION E of the polymer of ethylene and ⁇ -olefin is typically in the range of from 0.1 to 40 g/10 min, preferably in the range of from 0.3 to 4 g/10 min.
  • the polymer of ethylene and ⁇ -olefin typically comprises up to 70 mole percent of ⁇ -olefin.
  • the impact modifier be selected from the group consisting of linear low density polyethylene (LLDPE), low density polyethylene (LDPE), ethylene-propylene terpolymer (EPT or EPDM) and ethylene- propylene rubber (EPR) .
  • LLDPE linear low density polyethylene
  • LDPE low density polyethylene
  • EPT or EPDM ethylene-propylene terpolymer
  • EPR ethylene- propylene rubber
  • the impact modifier is LLDPE and has a melt flow index ASTM D1238 CONDITION E in the range of from 0.5 to 80 g/10 min, more preferably in the range of from 4 to 40 g/10 min.
  • the LLDPE typically has a density in the range of from 860 to 930 kg/m 3 , more preferably 890 to 920 kg/m 3 .
  • the block copolymer of at least one styrenic monomer and at least one olefinic or diolefinic monomer be grafted with from 0.1 to 20, more preferably 1 to 6, mole percent of a carboxylic acid, acid anhydride or sulphonate functionality.
  • the multivalent metal cations may be residues from catalysts used in the manufacture of the matrix polymer or impact modifier.
  • the multivalent metal cations may also be in the form of acid acceptors used in the compounding of the matrix polymer or impact modifier.
  • acid acceptors useful in providing multivalent metal cations are zinc oxide, zinc stearate and calcium stearate. It is preferred that the multivalent metal cation is provided in the form of zinc stearate in amounts in the range of from 100 to 3000 ppm based on the total weight of polymer. While not wishing to be bound by theory it is believed that the block copolymer forms an interface between the matrix polymer and the impact modifier.
