Density and viscosity of poly(ethylene glycol) nonylphenyl ether (PEG-NPE) saturated with supercritical carbon dioxide (SC CO 2 ), as well as the interfacial tension in the PEG-NPE-SCCO 2 system, were evaluated for the temperature range of 323 K to 343 K and pressures of 10.0 to 25.5 MPa. Remarkable
## SYNOPSIS A new method is presented for controlling the rate of antibody ( Ab) release from a n inert matrix composed of poly (ethylene-co-vinyl acetate) ( EVAc) , a biocompatible polymer that is frequently used to achieve controlled release. Using supercritical propane, a parent EVAc sample ( M
Poly(ethy1ene terephthalate) copolymers were prepared by melt polycondensation of dimethyl terephthalate and excess ethylene glycol with 10- 40 mol% (in feed) of poly(ethy1ene glycol) (E) and poly(tetramethy1ene glycol) (B), with molecular weight (MW) of E and B 200-7500 and 1000, respectively. The
