Poly(amide-b-ethylene oxide) copolymers were presented in 1990 as a promising membrane material [43]. These block copolymers were developed in 1972 but in 1981 began to be used for commercial purpose under the trade name Pebax , produced by ATOCHEM [44] (now ARKEMA). Another important group of segmented poly(ester)s used for membranes are block copolymers based on PEO and PBT (poly(butylene tereph-thalate), known under commercial name of Polyactive [45]. By changing the polyamide and polyether segment, molecnlar mass and the content of each block, the mechanical, chemical, and physical properties are nicely tnned as well [46]. 

The CO2 extraction from flue gases would be econonucally feasible if the membranes can be produced at a low price. Pebax polymers can give an opportunity to produce low cost membranes, since they are industrially produced and are easily processable by extrusion into thin films of good quality according to the website of Arkema (www.pebax. com). Such films could be laminated onto a microporous support for a production of... 

Among the many deals, only a few may be mentioned here. Arkema and Ciba Specialty Chemicals signed a global cooperation agreement enabling Ciba to distribute Arkema s Pebax permanent antistatic agents. They are polyether block amides intended for use in ABS, polystyrene and PVC. The two companies are also co-operating in research and development in the same area. Ciba has also become the exclusive distributor outside Asia of Kanebo Chemical s silver-based antimicrobial products for polymers. They are said to be effective, safe and heat-resistant to over 200 °C.

Interesting advances in the field of GS membrane materials are polymers with high-free volumes, such as poly(l-trimethylsilyl-l-propyne), poly(4-methyl-2-pentyne), and polymers of intrinsic microporosity [108]. Regarding the emerging application of CO2 capture, the copolymer class Pebax (Arkema) showed promising results. For instance, Bondar et al. [109] reported interesting values of CO2/N2 and CO2/H2 selectivity for different grades of Pebax membranes.
