Abstract: Gels and gel-containing materials, including hydrogels, are described. A gel can be formed by blending polyacrylic acid (PAA) and a polyglycol, such as polytetramethylene ether glycol (PTMEG) at room temperature and, in some cases, without using a catalyst. The blend material can be used to form soft or hard materials, films and particles. The blend material can be combined with vinyl monomers and polymerize to form a hydrogel. The hydrogel can have a high mechanical strength and high water absorbency.

Abstract translation: 描述了凝胶和含凝胶的材料，包括水凝胶。 凝胶可以通过在室温下混合聚丙烯酸（PAA）和聚乙二醇（例如聚四亚甲基醚乙二醇（PTMEG））形成，并且在一些情况下不使用催化剂。 共混材料可用于形成软或硬材料，薄膜和颗粒。 该混合材料可以与乙烯基单体结合并聚合形成水凝胶。 水凝胶可以具有高机械强度和高吸水性。
