Abstract:
1. A process for preparing a functionalized polyolefin, said process comprising the following steps: A) grafting onto the backbone of a polyolefin at least one compound comprising at least one amine-reactive group to form a grafted polyolefin at a temperature from 130° C. to 170° C.; and B) reacting a primary-secondary diamine, with the grafted polyolefin, and selected from compounds of structure (I) high density polyethylene, low density polyethylene, linear low density polyethylene, homogeneously branched linear ethylene/alpha-olefin interpolymers, homogeneously branched substantially linear ethylene/alpha-olefin interpolymers, and combinations thereof, and wherein step A takes place in an extruder, and step B takes place in a gear pump.
