  • Publication number: 20080227936
    Abstract: The present invention provides a method for supporting a nonmetallocene olefin polymerization catalyst, comprising the following steps: a carrier reacts with a chemical activator to obtain a modified carrier; a magnesium compound is dissolved in a tetrahydrofuran-alcohol mixed solvent to form a solution, then the modified carrier is added to the solution to perform a reaction, then filtered and washed, dried and suction dried to prepare a composite carrier; a nonmetallocene olefin polymerization catalyst is dissolved in a solvent, and then reacts with said composite carrier, then is washed and filtered, dried and suction dried, to prepare a supported nonmetallocene olefin polymerization catalyst. The present invention further relates to a supported nonmetallocene olefin polymerization catalyst as prepared by this method.

  • Patent number: 5981650
    Abstract: Cold-seal adhesives are disclosed that contain no natural rubber and are capable of forming dry coatings on flexible films which adhere to one another with commercially acceptable packaging strength at room temperature by pressure contact, but also allow such layered substrata to be reeled into rolls and stored for extended periods of time without blocking. The flexible films are usable in forming packages, particularly for comestibles and pharmaceuticals, without need for heat sealing. Such cold-seal adhesives are aqueous dispersions containing 30 to 55 percent of a polyurethane ionomer reaction product, having a T.sub.g of between about -50 to 10.degree. C., of a mixture of (a) a blend of between 0 and 40 percent polyester polyol and between 60 and 100 percent polyether polyol, (b) aliphatic diisocyanate and (c) dimethylol propionic acid and preferably containing 0.05 to 4 percent of grafted amorphous silica.
