摘要:
The present disclosure provides an ink-jet ink comprising an aqueous ink vehicle and an aqueous dispersion, the aqueous dispersion comprises a colorant and a polyurethane dispersant, wherein said polyurethane dispersant is comprised of a polymer having a cross-linkable moiety, wherein the cross-linkable moiety is cross-linked with a cross-linking agent.
摘要:
Inkjet inks are described that have, as a principal component, a crosslinked poly-urethane dispersoid binder additive. These inks can be used for printing on different media, and are particularly suitable for printing on paper.

摘要:
A method for the preparation of supported Ziegler-Natta catalysts comprising contacting a transition metal alkoxide and/or siloxide compound with a magnesium-containing reagent. The magnesium reagent is prepared in the presence of a magnesium chloride support utilizing an anhydrous and oxygen-free mixture of magnesium halide and magnesium metal, slurried in a hydrocarbon solvent. A halogenated hydrocarbon is added to produce the magnesium-containing reagent. Thereafter the transition metal alkoxide and/or siloxide compound is mixed with the slurry. An alkylating agent is added to form an active supported olefin polymerization catalyst.
