In the sixth chapter, according to our nations situations, a probing study on the development and application of natural mordenite was carried out at the aim to develop a new adsorbent carrier and reduce the cost of adsorbent preparation. The characters of natural mordenite were chemically changed by an acid. The effects of the acid solution concentration, temperature, mordenite size and treatment times on the physico-chemical characters of mordenite were undertaken. The adsorption equilibrium of CO on the character-changed natural mordenite was measured.

The aim of this study was to develop a novel amphiphilic functional block poly(ε-caprolactone) bearing ketone groups MPEG-b-P(OPD-co-CL. 2-oxepane-1, 5-dione was copolymerized with ε-caprolatone in which methoxy poly (MPEG, Mn=5 000) and stannous octoate were used as initiator and catalyst, respectively. The syntheses were conducted by bulk and solution polymerization. 1H NMR results showed that peak position and splitting of the polymers synthesized through solution polymerization were consistent with theoretical data, demonstrating the products were designed block copolymers. While in the bulk polymerization, polymer peak position was changed due to their high reaction temperature, suggesting their structural variation.
