High pressure laboratory JKU Linz
Institute for Chemical Technology of Organic Materials


Laboratory for olefin polymerization

The laboratory has been installed in cooperation with Prof. Günter Weickert from PRT GmbH in the years 2010/2011.
Since 2011 we are able operate one of the most accurate polymerization laboratory of the world.
