configurational sequence

in polymers
The whole or part of a @C00946@ comprising one or more species of @C01255@ in defined @ST06775@.
Configurational sequences comprising two configurational units are termed diads, those with three such constitutional units @C01287@, and so on. In order of increasing @ST06775@ lengths they are called tetrads, pentads, hexads, heptads, octads, nonads, decads, undecads, etc.
