Poly(methy1 methacrylate) with oligodimethylsiloxane grafts (MMA-g-DMS) was prepared by copolymerization of a dimethylsiloxane (DMS) macromonomer with methyl methacrylate (MMA). Two glass transition temperatures (T,) were observed at about 120Β°C and -127 "C in all graft copolymer membranes. Transmis

## Abstract **Summary:** Cellulose alkyl esters such as ethyl, butyryl, pentyl, and heptyl cellulose with different numbers of carbon in the alkyl ester group were synthesized for the separation of a mixture of benzene/cyclohexane (Bz/Chxβ=β5/95 w/w) with a low concentration of benzene. All of cell
