Title:
CATALYST COMPOSITIONS
Document Type and Number:
Japanese Patent JP3872808
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide novel catalyst compositions useful for polymerizing ethylene, acyclic olefins, and/or selected cyclic olefins, and optionally selected olefinic esters or carboxylic acids, and other monomers.
SOLUTION: Transition metal compounds such as Ni, Co, Fe, and Pd, and two nitrogen atoms, or nitrogen and phosphorus atoms are used as ligands. Compositions on rectangular plane steric configuration for a ligand with two seats having enough three-dimensional bulk on both sides of a coordination plane as a catalyst. Since some of the polymerizations exhibit some characteristics of living polymerizations, block copolymers can be readily made. Many of the polymers produced are often novel, particularly in regard to their microstructure, which gives some of them unusual properties. Numerous novel catalysts are disclosed, as well as some novel processes for making them. The polymers made are useful as elastomers, molding resins, in adhesives, etc.
