Abstract
A method of manufacturing a polyolefin solution continuously and in a stable manner with a high yield which comprises heading a polyolefin resin with a liquid composed of a solvent for the polyolefin resin, and is characterized in that; (1) a continuous kneader having a self-cleaning action is used, and (2) a starving state is maintained in the internal sections of the header at a polyolefin resin feed section, a liquid feed section, and the section in which the kneading of the polyolefin resin and the liquid is initially carried out.
