Infixes copolymers

Similarly to homopolymers, source-based nomenclature has been applied to copolymers [4]. The principal problem is to define the kind of arrangement in which various types of monomeric units are related to each other. Seven types of separate arrangements have been defined, which are shown in Table 1, where A, B and C represent the names of monomers. The monomer names are linked either through an italicized qualifier or connective (infix), such as -CO- , to form the name of the copolymer, as in poly(styrene-co-acrylonitrile). The order of citation of the monomers is arbitrary. 

For copolymers, a connective (infix) is inserted, which depends on what is known about the arrangement of the constitutional units. 

V In copolymer nomenclature, descriptive lowercase italic infixes may be used. These include alt, blend, block (or b), co, cross, graft (or g), inter, per, stat, and ran. 

Copolymers are named by writing the prefix poly , followed by the names of the actual or hypothetical monomers an infix, called a connective, is placed between them that indicate the type of sequential arrangement of the constitutional units within the chains.
