Synthesis of Hydrophilic Crosslinked Poly (vinyl alcohol) s Comprising Poly (ethylene glycol) as a Crosslinker

New hydrophilic crosslinked polymers comprising poly (vinyl alcohol) (PVA) and poly (ethylene glycol) (PEG) units were synthesized using sulfuric acid as a dehydration catalyst. When the molecular weight of PEG unit was high, the degree of the reaction was low. In contrast, a high degree of the reac...

Description
Summary:New hydrophilic crosslinked polymers comprising poly (vinyl alcohol) (PVA) and poly (ethylene glycol) (PEG) units were synthesized using sulfuric acid as a dehydration catalyst. When the molecular weight of PEG unit was high, the degree of the reaction was low. In contrast, a high degree of the reaction was attained when a low molecular weight PEG was used as a crosslinker.
