Abstract
UN POLIMERO, SOLUBLE EN AGUA, SUSTANCIALMENTE LINEAL SE HACE POR COPOLIMERIZACION DE UNA MEZCLA SOLUBLE EN AGUA DE MONOMEROS MONOETILICAMENTE INSATURADOS QUE COMPRENDEN MONOMEROS DE ACIDO CARBOXILICO, TALES COMO ACIDO ACRILICO Y UN MONOMERO HIDROXILICO DE LA FORMULA CHR1==CR2-Y-MA-OH EN DONDE R1 ES HIDROGENO O CARBOXIDO, R2 ES HIDROGENO, CARBOXIDO O METIL, Y ES O, CH2O O COOM M ES ALKILENOXIDO Y A ES AL MENOS 5. ESTE POLIMERO PUEDE SER ENLAZADO, GENERALMENTE DESPUES DE SER CONFORMADO MEDIANTE EXTRUSION U OTRO MEDIO DE CONFORMACION DE OTRA SOLUCION ACUOSA DEL POLIMERO PARA FORMAR ENLACES ENTRE LOS GRUPOS CARBOXIL O HIDROXIL. LOS ELEMENTOS CONFORMADORES PUEDEN TENER UNA ALTA ABSORCION DE AGUA Y PUEDEN ESTAR EN LA FORMA DE POR EJ. FIBRAS O PELICULAS.
