Interaction between a Side Chain Crystalline Block Copolymer and Wax

To solve these issues, the use of various additives has been proposed. In recent years, we have synthesized a block copolymer of acrylate monomers with long alkyl side chain and solvophilic monomers. The SCCBC, in particular, exerts a very remarkable dispersant effect for a concentrated PE particle dispersion. In this study, we have investigated the influence of the addition of the SCCBC on the crystallization of model wax/oil mixtures, and the temperature dependence on its rheological properties. Examination of the temperature dependence of viscosity or viscoelasticity revealed that the addition of SCCBC prevents the wax/oil mixed system from losing fluidity, even at the low temperatures at which wax would normally solidify. The non-solidification and fluidization effects of the model wax/oil mixed system, described herein, will be helpful in reducing blockages in pipelines for crude oil and in reducing the accumulation of sludge at the bottom of oil storage tanks.
