Abstract: This invention relates generally to crystalline polypropylene polymers and methods for their production. Specifically, this invention relates to crystalline polypropylene polymer compositions comprising both propylene homopolymers and propylene copolymers. The compositions are prepared using metallocene catalyst systems comprising at least two metallocenes in a polymerization process that involves the sequential or parallel polymerization of propylene homopolymers and copolymers using propylene with a small amount of comonomer, preferably ethylene. The resulting polymers are excellent for use in the production of biaxially oriented films. Films prepared with these propylene polymers have a significantly broader processability range and can be evenly stretched at lower temperature compared to films prepared from traditional polypropylene polymers.

Abstract: Maghnia or Mostaganem bentonites, are activated by contacting the Maghnia or Mostaganem bentonite with an acid solution of selected concentration and then drying the Maghnia or Mostaganem bentonite to form an activated bentonite catalyst. This activated bentonite catalyst may be used to polymerize a vinyl, acrylic, cyclic ether, aldehyde, lactone or olefin monomer. In a further embodiment, a perflourinated amine or diamine is synthesized by contacting a Maghnia or Mostaganem bentonite with an acid solution of selected concentration, drying the Maghnia or Mostaganem bentonite, and absorbing a secondary amine with the Maghnia or Mostaganem bentonite to form a perflouroamide iodide salt. The perflouramide idodide salt can then be extracted with a polar solvent and neutralized by the use of a basic solution.
