The technological revolution of single-sited and metallocene catalysts accelerated through the 1990s with increasing patent filings. The revolution continues with the advent of "post-metallocene," single-sited catalysts. However, commercial applications of these polymers has been slower than anticipated due to processing problems associated with narrow, molecular-weight distribution resins.    Global markets for single-sited catalyst (SSC) and metallocene polymers are projected to increase through 2010; total market share is predicted to be less than 15% for polyethylene (PE) and 6% for polypropylene (PP). Ziegler-Natta and advanced Ziegler-Natta polymers will remain the dom
