During the controversy over the question whether polymeric substances, which show colloidal properties in solution, are to be considered as molecules or as particles built up from many small molecules, the question was raised whether soap solutions might not serve as the model for polymeric colloids. It was in fact known that soap solutions owe their colloidal properties to a reversible association of the fatty acid anions or molecules. It became however ever more clear that the polymeric colloids must be considered as macromolecules — that is to say many monomers are bound together by ordinary valencies to form a polymer. It can be deduced from many properties of the polymers that these are indeed macromolecules. 

Polymers are large, usually chainlike molecules that are built from small molecules called monomers. Polymers form the basis for synthetic fibers, rubbers, and plastics and have played a leading role in the revolution brought about in our lives by chemistry during the past 50 years. (Many important biomolecules are also polymers.)... 

Polymers are large molecules formed by the repetitive bonding together of many smaller molecules, called monomers. As we ll see in the next chapter, biological polymers occur throughout nature. Cellulose and starch are polymers built from small sugar monomers, proteins are polymers built from amino acid monomers, and nucleic acids are polymers built from nucleotide monomers. The basic idea is the same, but synthetic polymers are much less complex than biopolymers because the starting monomer units are usually smaller and simpler. 

Polymers are a class of substances that consist of very large molecules, macromolecules, built up from many multiples of small molecules, monomers. They can be synthetic (polythene, nylon) or natural (protein, rubber), and occur widely in nature as vital components of living organisms. Most polymers, both natural and synthetic, have a framework of linked carbon atoms. These are strong because the carbon atoms are linked by covalent bonds. The long molecules themselves are linked by some of the weak bonds listed in Table 3.1 and are... 

Staudinger postulated that such macromolecules were built up from small so-called monomer units that were linked together by normal chemical binding forces and not by physical associations of small molecules. This hypothesis was by no means self-evident at that time and therefore became an object of many academic controversies between chemists and physicists until about the late 1930s. In the meantime Staudinger s basic ideas of macromolecular chemistry are generally accepted. 

Polymerization is the process of joining together small molecules by covalent bonds to produce high-molecular-weight polymers. Both natural aud synthetic polymers are built from these simple small molecular units known as monomers. However, the range of properties that can be achieved depends on the strategy used to assemble these units. This chapter covers many of the synthetic strategies used to build polymers and provides examples of several of the commercial polymers made with these techniques.
