  • Patent number: 4794145
    Abstract: A process is provided for metallating ethylene polymers which have polymerized therein a minor amount of nonconjugated diene. Metallation is accomplished with a blend of three metallating reagents: (a) an alkyllithium compound; (b) a potassium alkoxide; and (c) a chelating tertiary diamine. The metallated polymers so prepared may be reacted with one or more anionically polymerizable monomers to form graft polymers or with a reagent such as carbon dioxide to form a functionalized polymer. When the anionically polymerizable monomer has two or more polymerizable sites, the metallated polymer is reacted with a modifying compound such as alpha-methylstyrene before it is reacted with the monomer(s). Certain of the graft polymers behave as thermoplastic elastomers whereas others are thermoplastic. The blend of metallating reagents may be used with any polymer having partial or complete unsaturation.

  • Patent number: 4707521
    Abstract: A process is provided for metallating crystalline ethylene polymers which have polymerized therein a minor amount of at least one nonconjugated diene and, optionally, a minor amount of at least one 1-olefin. Metallation is accomplished with an alkyllithium compound and at least one activating reagent after a slurry of the copolymer in a nonreactive, saturated, nonpolar hydrocarbon solvent is first heated to a temperature greater than 80.degree. Centigrade to provide the polymer with an expanded settling volume greater than its original settling volume. Metallation may be accomplished either at that temperature or at a lower temperature following cooling of the slurry. The activating reagents include potassium alkoxides, and chelating tertiary diamines. The metallated polymers so prepared may be reacted with (a) one or more anionically polymerizable monomers to form graft polymers or (b) a reagent such as carbon dioxide to form a functionalized polymer.
