pseudo-copolymer

Also contains definition of: statistical pseudo-copolymer

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.
