METHOD FOR PRODUCING MODIFIED POLYOLEFIN SOLUTION

摘要

A method for producing a modified polyolefin solution, which can reduce polymer loss, solvent loss and further number of steps, and thus has excellent productivity and economic efficiency in a series of steps, wherein an alpha -olefin is polymerized to obtain a polyolefin, followed by modification with a modifying agent to produce a modified polyolefin solution, characterized by comprising a step wherein an alpha -olefin is polymerized in the presence of polymerization catalyst in liquid phase to obtain a polyolefin as a polymer solution or slurry state and a step wherein thus obtained polymer is reacted with a modifying agent to modify a polyolefin, and in that the polymer is not isolated, not recovered, nor substantially dried, in a method for producing a modified polyolefin solution by modification, using a modification agent, of a polyolefin obtained by polymerization of an alpha -olefin.
