<p><P>PROBLEM TO BE SOLVED: To simply and safely provide at a low cost an unsaturated carboxylic acid-grafted polyolefin exhibiting excellent adhesive properties not only to a plastic material but also to different kinds of materials and excellent qualities such as a hue and the like. <P>SOLUTION: The manufacturing method for the modified polyolefin comprises a graft reaction step of causing an unsaturated carboxylic acid to graft onto a polyolefin in a halogen-containing solvent having a boiling point of 120°C or lower under normal pressure and an isolation step of isolating the modified polyolefin as a reaction product by feeding a reaction solution after the graft reaction to a drum drier and volatilizing and removing the solvent. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
