Definitions

  • Polypropylene especially highly isotactic polypropylene, has been used in many applications in the form of molded articles, film, sheet, etc., because it is excellent in molding processability, toughness, moisture resistance, gasoline resistance, chemical resistance, has a low specific gravity, and is inexpensive.
  • polypropylene is poor or inadequate in heat resistance, stiffness, impact resistance, and scratch resistance.
  • thermoplastic polyesters such as polyethylene terephthalate are widely used as engineering thermoplastics in the fields of automobile parts, electrical components and electronic parts, because such polymers have high heat resistance, stiffness, strength, solvent resistance, and oil resistance. It would, however, be desirable to further improve the molding processability, toughness, notched impact resistance and chemical resistance of these plastics.
  • polyesters are disadvantaged in that these plastics have higher specific gravity and are more expensive than polypropylenes.
  • the unsaturated organic compound is used in an amount such that, after grafting to the polyolefin elastomer, it constitutes by weight at least 0.01 percent, preferably at least 0.05 percent, more preferably at least 0.1 percent, more preferably at least 0.5 percent, and most preferably at least 1.0 percent based on the weight of grafted polyolefin elastomer
  • the maximum amount of unsaturated organic compound content can vary to convenience, but typically constitutes by weight less than or equal to 20 percent, preferably less than or equal to 15 percent, more preferably less than or equal to 10 percent, more preferably less than or equal to 5 percent, and most preferably less than or equal to 2 percent based on the weight of the grafted polyolefin elastomer.
  • the impact modifier component (d) is a polyolefin elastomer, it may be the same as or different from the polyolefin elastomer selected for graft modification as component (c). In addition, mixtures of the foregoing rubbery polymers may be employed if desired.
  • Preparation of the polymer blend compositions of this invention can be accomplished by any suitable mixing means known in the art, including dry blending the individual components and subsequently melt mixing, either directly in the extruder used to make the finished article (for example, the automotive part), or pre- mixing in a separate extruder (for example, a Banbury mixer). Dry blends of the compositions can also be directly injection molded without pre-melt mixing.
  • PET is polyethylene terephthalate which is commercially available as LIGHTERTM C88 from INCA having an intrinsic viscosity of 0.77 deciliter per gram (dl/g) measured according to INCA analytical method 1/MA/1/002 and a density of 1.39 g/cm 3 ;
  • MAH-g-EPDM is maleic anhydride grafted on to ethylene propylene rubber with some diene monomer which is commercially available as ROYALTUFFTM 465 from U ⁇ iroyal Chemical Company;
