Book ChapterDOI
The Equilibrium Swelling Behavior of Porous and Non-Porous Hydrogels
TL;DR: In this article, the physicochemical models utilized to analyze the equilibrium swelling behavior of neutral and ionic, porous and non-porous hydrogels are reviewed, with emphasis given to the determination of the molecular weight between crosslinks.
Journal ArticleDOI
A Model for Interdiffusion at Interfaces of Polymers with Dissimilar Physical Properties
TL;DR: In this paper, a model was developed for interdiffusion at interfaces of polymers with dissimilar physical properties based on the assumption that the monomeric friction coefficients of the two polymers are identical but a strong function of the matrix composition.
Journal ArticleDOI
Mucoadhesive poly(vinyl alcohol) hydrogels produced by freezing/thawing processes: Applications in the development of wound healing systems
TL;DR: Ultrapure poly(vinyl alcohol) (PVA) hydrogels prepared by exposing an aqueous solution of 15 or 20 wt% PVA to repeated cycles of freezing for 6 or 12 h at -20 degrees C and thawing for 2 hours at 25 degrees C exhibited the largest work of adhesion.
Journal ArticleDOI
PH-responsive hydrogels with dispersed hydrophobic nanoparticles for the oral delivery of chemotherapeutics
TL;DR: The cytocompatibility of the polymer materials were assessed using cell lines representing the GI tract and colon cancer and were noncytotoxic at varying concentrations and exposure times.
Journal ArticleDOI
Preparation of poly(methacrylic acid-g-ethylene oxide) microspheres
TL;DR: In this paper, a copolymerisation radicalaire en suspension, apres gonflement dans l'eau, les particules ont un diametre compris entre 10 and 60 μm and sont stables entre pH 4,75 and 7,4.
