Poly(ethylene oxide) (PEO) was used to prepare thin polymer films containing clotrimazole (CT) utilizing hot-melt extrusion (HME) technology. Films containing PEOs of two different molecular weights and the drug were investigated for solidstate characteristics, moisture-sorption, bioadhesivity, mech
Coefficients of expansion and int\_\_ernal pressures (P3 have been measured for samples of poly(ethylene oxide) of molecular weight (M,) 2000, 6000 and 20000. The values of P~ found for the solids (P~ < l0 s Pa, 10 ยฐ) are low compared to those found for the liquids (P~ = 5 x 10 s Pa, 70ยฐ).
Poly(ethylene oxide~diene-cthylene oxide) triblock copolymers were synthesized by anionic polymerization and characterized by FT-IR, DSC and low angle X-ray scattering. Both glass transition temperature of the elastomer segment and melting temperature of the poly(ethylene oxide) (PEO) crystalline ph
