Plastics, just like any other material, have experienced a rapid development over the last decade and it is vital for chemical engineers to have a single source documenting all these developments. Arranged according to the chemical constitution of polymers, this second volume of a four-volume set reviews the developments that have taken place in the last decade, focusing on common types of polymers belonging to the class of water soluble polymers. It covers a wide range of applications including food, cosmetic, medical, lithography and ink jet printing, agricultural, wastewater cleaning, and oilfield chemicals.
