I'm going to try something new this year - keeping a separate page going that lists the current state of open access to polymer literature. (This is an idea I've been kicking around since my previous post on the subject back in October.) There is a tab at the top this page with what I have so far (heavy on the Elsevier journals since they were easy to tabulate), but I will keep adding to the page as new articles are available and remove them when they no longer are. As is often the case, publisher will provide free access for a limited time. And I am calling this "free access" rather than "open access" to denote the difference. Open access, in my mind, is for all eternity, or at least there are no plans to remove the access.
Any error and omissions are my own fault, although I am (naturally) going to skew the selection towards areas that I have interest in. An article on a new catalyst to convert a alkene into an alkyne? Nah. An article on a new catalyst to polymerize an alkene? Definitely.
Lastly, as I make significant changes to the page, I will put a short note here so that you don't have to keep looking at the other page. Granted, this assumes that you are using an RSS reader or you have this page bookmarked and read every post I create, which is scary thought.
