摘要: A water-soluble polymer having a low polydispersity index and controlled molecular weight can be prepared by oxidative degradation and shearing of a water-swellable crosslinked polymer or by hydrolysis of the crosslinked polymer to a high molecular weight soluble polymer, followed by oxidative degradation of the high molecular weight polymer.

摘要: A process is described for recycling dry aqueous fluid absorbent polymer fines into a process that includes a polymerization step for making the aqueous fluid absorbent polymer. The process requires recovering the dry polymer fines, mixing the fines with a polymerizable monomer solution for making the aqueous fluid absorbent polymer and polymerizing the mixture of fines and monomer to form the aqueous fluid absorbent polymer. In the process the fines are incorporated into the new polymer gel and becomes indistinguishable therefrom. The gel may then comminuted into a particulate dried and then separated into a portion having a desired minimum particle size in a fines portion having less than the desired size. The fines portion is then recycled up to about 30 percent by weight based on gel solids may be recycled for the preferred polyacrylate based aqueous fluid absorbent polymer.

摘要: A durable, conformable, absorbent, hydrophilic, polymeric latex foam composition having a free absorbent capacity of at least 5 grams of a 0.9 weight percent aqueous saline solution per gram of foam and capable of vertically wicking said aqueous saline solution to a height of greater than about 5 cm. In a preferred embodiment, after compression, the latex foam composition remains thin until wet, whereupon it expands and exhibits a high free absorbent capacity and high vertical wicking height.
