Pre-modification of Hyper-crosslinked Polymers

It was also reported that HCP networks can be used as stabilizers to produce metal nanoparticles. A hyper-crosslinked polystyrene network (HPS), obtained from a styrene-divinylbenzene copolymer, acts as a matrix to synthesize Co nanoparticles owing to its nano-sized rigid cavities of comparable size. These cavities ean eonsume several Co eomplexes and can control the growth, particle size and size distribution of Co nanopartieles.  

Various Brunauer-Emmett-Teller (BET) surface areas have been obtained for hyper-crosslinked networks of polypyrrole using diiodomethane, triiodo-methane and triiodoborane by erosslinking with CH2, CH and B erosslinkers, respectively. It was also observed that HCPs reduced with metal partieles like Li possess inereased selectivity towards CO2 over CH4, although there was a decrease in surface area as metal partieles fill the pores (not post-synthesis).
