Statistical co-
crystallization of different
constitutional repeating units which may either belong to the same
copolymer chains (
copolymer isomorphism) or originate from different
homopolymer chains (
homopolymer isomorphism). Isomorphism is a general term: in the strict sense, the crystal structure
is essentially the same throughout the range of compositions; in isodimorphism or
isopolymorphism, there are two or more crystal structures, respectively, depending
on composition.
