A large molecule made from many repeating units joined together See also monomer
A polymer is a long chain molecule or a complex 3-dimensional lattice produced by the reaction of simple compounds with each other. There are two types of poymerisation. The first, where compounds open a double bond and link together via the radicals formed is called addition polymerisation. eg. the poylmerisation of propylene to polypropylene:
a substance that consists of large molecules formed from smaller molecules in repeating structural units (monomers). In oilfield operations, various types of polymers are used to thicken drilling mud, fracturing fluid, acid, water, and other liquids. See micellar-polymer flooding, polymer mud. In petroleum refining, heat and pressure are used to polymerize light hydrocarbons into larger molecules, such as those that make up high-octane gasoline. In petrochemical production, polymer hydrocarbons are used as a feedstock for plastics. ...
A macro-molecular substance made up of many repeating smaller units (monomers) bonded together in chain-like sequences which may or may not be cross-linked. Some monomers such as ethylene (the related polymer is polyethylene) are simple molecules; others, such as the nucleotides of which DNA and RNA are constructed, are large and complex.
