2127979 9314265 PCTABS00024 Porous materials having a range of pore sizes are given desired characteristics by selective deposition in the large pores of particulate treatment agents. Thus some characteristics are achievable by control variation of pore size distribution (e.g. sample uniformity, liquid filtration properties) while others depend on specific attributes of the treatment agents (e.g. response to calendering, catalysis, security marking, adhesion properties). |
