ABSTRACT:
A relatively dilute aqueous solution of an amide polymer such as polyacrylamide when treated with a small amount of a hypohalite salt solution reacts under ambient conditions to form a firm gel. Such firm gels are useful replacements for the aqueous gels prepared from vegetable gums and conventionally employed in air freshener devices and the like.
