Polymerization also denotes the formation of The equilibrium mixture behaves chemically much as would the small molecules by themselves, because the removal of some by chemical reaction shifts the equilibrium in such a way as to disassociate more of the aggregate in accordance with the law of mass action. Clinical Chemistry Trainee Council The Clinical Chemistry Trainee Council serves as a unique program for residents and fellows in laboratory medicine by providing them with free educational materials and interactive tools to help and guide them to a successful career. The term signifies the reverse of dissociation, but is not commonly used for the formation of definite adducts by colligation or coordination. "association" (chemistry) definition: any process of combination (especially in solution) that depends on relatively weak chemical bonding. Polymerization also denotes the formation of larger units by the union of like small units but usually with chemical bonds between the smaller units. An ice crystal is a giant network of water molecules held together by hydrogen bonds.
