Also contains definition of: statistical pseudo-copolymer
https://doi.org/10.1351/goldbook.P04926
An irregular polymer, the molecules of which are derived from only one species of monomer but which display a variety of structural features more appropriate for description in copolymer terms.
Note:
Where appropriate, adjectives specifying the types of '@C01335@' may be applied to 'pseudo-@C01335@'. The term statistical pseudo-copolymer, for instance, may be used to describe an @I03257@ in the molecules of which the sequential distribution of configurational units obeys known statistical laws.
