Title: pseudo-copolymer
Long Title: IUPAC Gold Book - pseudo-copolymer
DOI: 10.1351/goldbook.P04926
Status: current

Definition
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 'copolymer' may be applied to 'pseudo-copolymer'. The term statistical pseudo-copolymer, for instance, may be used to describe an irregular polymer in the molecules of which the sequential distribution of configurational units obeys known statistical laws.
