Recently, the polymer science field has focused on the role of polymers as membrane materials with precise, well-ordered structures through the development of defined synthesis and analysis of polymers. Among these well-ordered polymers are the hyperbranched polymers (e.g. hyperbranched polyimides). Part of the interest in such polymers is due to the expectation that they could have different properties as compared to common linear polymers. Also, cross-linked polyimides have attracted much attention from researchers, as can be judged by a high number of publications. [Pg.3]

This chapter presents a review of numerons publications devoted to the concept and synthesis of hyperbranched and cross-linked polyimides. Also, gas permeation properties of these polymers are considered in detail. [Pg.6]

Cross-linked (Type II) and hyperbranched (Type III) polyimides can be prepared for the use as gas separation membranes. There are no dendrimers and dendrons known, which would form free-standing membranes. Therefore, we focus on the synthesis of cross-linked (Type n) and hyperbranched (Type III) polyimides. [Pg.7]
