Title:
OXYFUNCTIONALIZATION OF POLYOLEFINS
Document Type and Number:
WIPO Patent Application WO2004099266
Kind Code:
A3
Abstract:
The present invention is a method for oxyfunctionalizing, that is, introducing oxygen functionality to, a polyolefin such as polypropylene and poly(ethylene-alt-propylene). The polyolefin is contacted with an oxygen source such as a persulfate and catalytic amounts of a metal porphyrin complex under mild conditions to yield an oxyfunctionalized polymer that has a polydispersity that is very similar to that of the starting polymer.
