El alcohol polivin\u00edlico (PVOH, PVA o PVAL) es un pol\u00edmero sint\u00e9tico soluble en agua. Tiene una f\u00f3rmula molecular idealizada [CH2CH (OH)] n. Se usa en la fabricaci\u00f3n de papel, dimensionamiento de urdimbre textil, f\u00f3rmula adhesiva de acetato de polivinilo (PVAC), varios recubrimientos y estabilizador de agente de engrosamiento y loci\u00f3n en la impresi\u00f3n 3D. Es incoloro (blanco) e ins\u00edpido. Por lo general, se proporciona en forma de cuentas o soluciones acuosas. Sin la adici\u00f3n externa de agente de reticulaci\u00f3n, la soluci\u00f3n de PVA se puede congelar repetidamente gelatinizadas para producir hidrogel ultra puro y biocompatible de alta resistencia, que se ha utilizado en una variedad de aplicaciones, como stents vasculares, cart\u00edlago, lentes de contacto, etc.<\/p>\n","protected":false},"excerpt":{"rendered":"
