The new 2009 ISI Impact Factors have just been released - here are the latest developments for polymer science:

Macromolecular Rapid Communications celebrates its first Impact Factor above 4 (4.3, +9%) reconfirming its position as #2 among all journals publishing mainly original research in general polymer science.

Journal of Polymer Science, Part A: Polymer Chemistry has increased its Impact Factor to 3.97, and with its upcoming relaunch and expanded scope to encompass all of modern polymer physics, Journal of Polymer Science, Part B: Polymer Physics has reached an Impact Factor of 1.59.

Macromolecular Chemistry & Physics enjoys another strong increase, again to the journal's highest value ever: 2.57 - reaffirming the position among the top-10 of journals publishing original research in general polymer science.

Macromolecular Bioscience, with an Impact Factor of 3.1, confirms its position among the top 10 polymer journals while also ranking among the top 5 biomaterials journals.

Plasma Processes and Polymers remains a leader among polymer science and fluids and plasma physics journals, with a significant increase to the journal's highest-ever Impact Factor of 4.04 (+38%).

Macromolecular Materials & Engineering has reached a new Impact Factor of 1.74, the second-highest value in the journal's history, confirming MME's position as the leading journal focusing on the design and processing of advanced polymeric materials.

Macromolecular Theory & Simulations, the only polymer science journal dedicated exclusively to theory and simulations, reached a 2009 Impact Factor of 1.68.

And following last year's excellent first rating, Macromolecular Reaction Engineering now could further increase this value by 40% to a new Impact Factor of 1.49 - thereby remaining the only high-quality journal dedicated to the field of polymer reaction engineering.
