The microporous texture of pitch-based spherical activated carbon(PSAC)containing iron and without iron was studied in order to investigate the effect of iron on the formation of micropore.It was showed that iron had no obvious influence on the distribution of micropore,while it made the specific surface area and pore volume of micropore decrease slightly.

Polyurethanes are versatile materials used widely in many applications. Annual production of polyurethanes is increasing day by day. The most important application of polyurethane covering its major market is polyurethane foam. Flexible and rigid foams are two major types of polyurethane foam used widely. Flexible and rigid foam samples were synthesized on lab scale by cup foaming. All samples were characterized by finding density of each sample. Cream, gel and rise time were also estimated for each sample. The chemical compositions of all polyurethane foam samples were characterized by FTIR analysis.

For increasing the toughness of polypropylene and expanding its applications,the modification mechanism polypropylene is discussed in this paper, and the inorganic particles (calcium carbonate)and organic plastic materials (polyethylene St) are used to modify the polypropylene in this article.The characterization of the polypropylene modified by calcium carbonate and St-modified shows much better toughness and mechanical strength than the pure polypropylene.
