GELS AND HYDROGELS
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 sof...

| description | 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.
Se describen geles y materiales que contienen gel, incluidos los hidrogeles. Se puede obtener un gel mezclando ácido poliacrílico (PAA) y un poliglicol, como politetrametilenglicol (PTMEG) a temperatura ambiente y, en algunos casos, sin un catalizador. El material mezclado se puede usar en la obtención de materiales blandos y duros, películas y partículas. El material mezclado se puede combinar con monómeros de vinilo y polimerizarse hasta formar un didrogel. El hidrogel puede tener una alta resistencia mecánica y alta absorbencia del agua. |
