摘要：
Disclosed is a method for the synthesis of sterically hindered polymeric antioxidants based on phenol type antioxidant monomers. The method includes polymerizing and alkylating a phenol containing monomer represented by the following structural formula: to produce a sterically hindered polymeric macromolecular antioxidant. X, R10 and q are as defined herein. The disclosed method is a simple, direct and economical process for the synthesis of sterically hindered polymeric macromolecular antioxidants.
