addition polymerization

[ə¦dish·ən pə‚lim·ə·rə′zā·shən]
(organic chemistry)
A reaction initiated by an anion, cation, or radical in which a large number of monomer units are added rapidly (a chain reaction) until terminated by some mechanism, forming a high-molecular-weight polymer in a very short time; an example is the free-radical polymerization of propylene to polypropylene.

The basis of modern synthetic rubbers lies in macromolecules synthesis by way of step- or chain-growth polymerization.
The workshop will cover subjects such as: fundamental principles of polymer chemistry and how they relate to the rational development of coatings formulations; how step-growth and chain-growth polymerizations work and why they lead to such remarkably different types of polymer systems; principles of emulsion polymerization--why this process is so different from solution polymerization--and how scientists have employed emulsion polymerization techniques to engineer complex multiphase structures with unique performance properties in paints and coatings.
