A study has been made into electrification of linear flexible-chain polymers extruded through metal and dielectric ducts. Most of the work concerns 1,4-polybutadienes prepared by anionic polymerization, with different molecular masses and molecular mass distributions. A pre-requisite for intense static electrification is the relaxation transition of the polymer from fluid into forced high-elastic state in which the polymer slides over the duct wall surface. The relation between electrification of polymers and their molecular mass, molecular-mass distribution, temperature, sliding velocity, and the duct length has been established. Electrification of polybutadiene in dielectric ducts and the effect of the chemical nature of polymers on their static electrification were also examined.
