Polyethylene glycol–polyvinyl alcohol (PEG-PVA) brand name Kollicoat IR (BASF) is a multifunctional excipient [1] used as a pill binder as well as a wet binder.

Oct 7, 2023 · According to the XRD studies, PEG has a significant plasticizing impact on PVA, as evidenced by the drop in crystallinity (X c) values from 31.24 to 25.45%. The thermal study reveals the reduction in the glass transition temperature T g from 89.2 to 60.6 °C.

Jul 2, 2019 · In this study, a novel poly (vinyl alcohol) (PVA)/poly (ethylene glycol) (PEG) scaffold was carefully designed via thermal processing and subsequent supercritical fluid (SCF) foaming.

Composition: PVA side chains grafted onto PEG 6000 backbone. combination of PVA and PEG into one molecule

Analytical methods for polyvinyl alcohol (PVA)-polyethylene glycol (PEG) graft co-polymer (INS 1209) were partially adapted from methods published by the United States Pharmacopoeia and the European Pharmacopoeia.

Nov 30, 2015 · PEG-PVA is a hydrophilic freely water-soluble polymer, comprised of 25% PEG and 75% PVA, wherein the vinyl alcohol moieties are grafted on a polyethylene glycol backbone, as shown in Figure 110. PEG-PVA is a spray dried powder of a high flowability recognizable by an angle of repose below 30°.

Sep 29, 2004 · The purpose of this study is to develop novel poly (vinyl alcohol) (PVA)/poly (ethylene glycol) (PEG) hydrogel blends and PVA-derived organic–inorganic hybrid materials and perform nanostructural characterizations.

Oct 6, 2015 · A double-network polymer hydrogel composed of chemically cross-linked poly (ethylene glycol) (PEG) and physically cross-linked poly (vinyl alcohol) (PVA) was prepared.

Polyvinyl alcohol grafted polyethylene glycol copolymer (e.g. Kollicoat® IR) and its combination with 40% PVA (e.g. Kollicoat® Protect) in addition to their instant release and moisture barrier profiles, have been investigated as matrices for direct compressions and wet granulation.

Apr 20, 2020 · In this work, shape-stabilized solid-solid phase change materials (PCMs) were fabricated by simply electrospinning polyethylene glycol (PEG) and polyvinyl alcohol (PVA). Owing to the strong hydrogen bonds and entanglement between those molecular chains of PEG and PVA, PEG was packaged by PVA.
