定義
ChEBI: An acrylate macromolecule, composed of repeating 2-hydroxyethyl 2-methylpropanoate units.
一般的な説明
Solid Poly(2-hydroxyethyl methacrylate) (pHEMA) is brittle, while pHEMA hydrogel is a soft material. Glass transition temperature for pHEMA hydrogels is reduced by increasing a content of water in the matrix. Macromolecular properties in pHEMA are characterized by non-covalent interactions of hydrogen-bonds among the polymer chains as well as the hydrated water molecules. The presence of polar groups of hydroxyl and carboxyl on each repeat unit makes this polymer compatible with water. The hydrophobic a-methyl groups of the backbone convey hydrolytic stability to the polymer and enhance mechanical strength of the polymer matrix.
