Grafted polyolefins useful as metal adhesion promoters |
| abstract |
An improved method for producing polypropylenes grafted with acrylic acid by means of reactive extrusion using an organic peroxide is disclosed, wherein the improvement comprises feeding the acrylic acid and the peroxide into the extruder downstream from the point where the polypropylene is introduced; wherein the acrylic acid is added at a feed rate greater than 25 pounds per hour, the. peroxide is added at a feed rate greater than 2 pounds per hour, and the total rate is greater than 500 pounds per hour; and whereby the PP-g-AA thus produced has a melt flow rate greater than about 200 dg per minute. |
