Polyvinyl chloride‐triethylene‐tetramine supported palladium complex (PVC‐TETA‐Pd) was prepared from polyvinyl chloride via simple method and the production cost of the complex was remarkably low. The complex was an efficient catalyst for Heck reaction. It was active for low activity substrates such as aryl bromides and aryl chlorides. The coupling of bromobeneze with styrene catalyzed by PVC‐TETA‐Pd afforded 99.8% yield of stilbene under the optimized reaction conditions. PVC‐TETA‐Pd could catalyze the Heck reactions in the presence of several different kinds of acid‐binding agents. Furthermore, the good reusability of PVC‐DTA‐Pd was also found for Heck reaction. © 2009 Wiley Periodicals, Inc. J Appl Polym Sci, 2010
