Effects of Molecular Structure of Poly(Olefin Sulfones) on Their Antistatic Performances
摘要
Abstract
Polysulfones as antistatic additives for fuel oil were synthesized from different olefins, polar monomers and sulfur dioxide. The influences of molecular structures and relative molecular masses of poly(olefin sulfones) on their antistatic performance were investigated. The results showed that antistatic effect of poly (α-alkene sulfones) with long side groups was significant, and poly (cyclohexene sulfone) with one side group on each C-C bond as antistatic additive was inactive. When the antistatic additive (poly (1 -decene sulfone) or poly (1 -hexadecene sulfone)) dosage was 2 mg/L, the conductivity increments of hydrotreated diesel fuel were 110 pS/m or 83 pS/m, respectively. The strong electrostatic interactions between carbonyl groups and sulfone groups in the molecules of poly (acrylic acid-1-decene sulfone) and poly(maleic anhydride-1-decene sulfone) result in their higher antistatic performance than that of poly (1 -decene sulfone). When the mole ratio of 1-decene to polar monomer, namely acrylic acid or maleic anhydride, was 10 : 1 and the antistatic additive dosage was 2 mg/L, the conductivity increments of the hydrotreated diesel fuel was 297 pS/m and 153 pS/m, respectively. The poly(olefin sulfones) with lower relative molecular mass showed higher antistatic performance than those with high relative molecular mass in the early days of storage, but the latter showed better performance in the late period of the storage.关键词
