Title:
METHOD FOR COUPLING POLYOLEFIN CHAINS
Document Type and Number:
WIPO Patent Application WO/2010/099645
Kind Code:
A1
Abstract:
Method for coupling polyolefin chains includes solution grafting or melt grafting polyolefin (100 pts. wt.) with a polyfunctional-containing alkene monomer (0-15 pts. wt.) in the presence of a second alkene monomer (0-15 pts. wt.) and an initiator (0.02-10.0 pts. wt.) at a determined temperature to obtain grafted polyolefin with a side chain comprising functional groups; then, by means of a solution-grafting or a melt-blending reaction, adding a polyfunctional organic coupling agent (0.1-20 pts. wt.) and an antioxidant (0-10.0 pts. wt.) to said grafted polyolefin (100 pts. wt.) at a specific temperature to obtain coupled polyolefin. Compared to the art, the method produces high-strength long-branched polyolefin with a controllable degree of coupling, at low cost and high production rates.
