Hydrogels are a continuously expanding class of pharmaceutical polymers designed for sustained or controlled drug release. The structure and intermolecular interactions in such systems define their macroscopic properties. The aim of this study was to investigate the mechanism of swelling, drug impre
Graft copolymers containing poly(ethy1ene oxide) side chains attached to a polyethylene backbone were prepared by coupling of poly(ethy1ene-co-acrylic acid) (PEAA) and poly(ethy1ene oxide) monomethyl ethers (MPEO) by esterification in o-xylene a t 14OoC. The MPEO side chains had molecular weights of
## Abstract Interpenetrating polymer networks (IPNs) of poly(ethylene oxide) (PEO) and a polyether substituted polysiloxane were synthesized containing variations of PEO content (35 and 65% dry network weight) and PEO systematically varied from low to high molecular weight (2,000, 8,000, and 20,000
