Polyacrylonitrile consists of an acrylic homopolymer made out of 100% acrylonitrile of high molecular weight (about 500.000 with an Mw/Mn ratio of 2.5). Acrylonitrile monomers are polymerised in an homopolymer of 100% acrylonitrile by a chain reaction mechanism. The polymer chain is made of a stable -C-C-C- chain with laterally CN- groups having strong dipole moments. Several neighbouring dipoles of the same and or different chains interact by coupling (electrostatic attraction). It is evident that steric hindrance of bulky comonomers (of an acrylic copolymer) severely interrupt these dipole pairings.
