Acrylic polymers,cid (IV); acrylonitrile (V); acrylamide (VI); and copolymers of these compounds. Copolymers of methacrylic acid and ethylene are described in Chapter 2. The important styrene-acrylonitrile and acrylonitrile-butadiene-styrene copolymers are discussed in Chapter 3 whilst acrylonitrile-butadiene copolymers are dealt with in Chapter 18.

Polyesters,of this chapter, polyesters are defined as polymers containing recurring -CO-O- groups in the main chain. It may be noted that this definition excludes polymers of esters such as vinyl acetate and methyl methacrylate since in these polymers the ester groups occur in side-chains and not in the main chain.

Aminopolymers,has been some commercial interest in thiourea-formaldehyde and aniline-formaldehyde polymers but these products are now of little importance. The aforementioned polymers form the contents of this chapter.
