Waterlock polymer

Chapter 14 expands the covei e of organic chemistry beyond that introduced in Chapter 12 to include the major fimctional groups. Ethylene glycol poisoning is used to illustrate some functional group chemistry of alcohols and carboxylic acids and reinforces the importance of the roles of acid-base chemistry and ionic bonding in this phenomenon. There is a new discussion of waterlock polymers and their applications, used as an example of the importance of polymers, are treated in some detail in this chapter. There is an expanded discussion of plastics recycling. 

Another variation on the luminol CL sensor for N02 was introduced by Collins and Ross-Pehrsson [12] where a solid-phase reagent was positioned below a PMT, across which the air under test is pumped. Of the hydrogel or polymeric sorbents investigated, a Waterlock superabsorbing polymer (hydrogel)... 

The polyacrylate (known as a superabsorbent polymer or SAP by the diaper industry) is distributed throughout the fluff pulp. Another name for these crystals is Waterlock . It is also used for plants to help retain water in the soil. The polyacrylate under pressure can hold an amount of liquid that is as much as thirty times its weight. This correlates to the compression (pressure) that occurs when a baby would sit or lie on the diaper. The polyacrylate allowed the manufacturers to reduce both the weight and thickness of the diaper by 50 percent and increase its absorbency.
