“…In our previous work, it was found that linear lowdensity polyethylene (LLDPE) surfaces could be easily modified by using side-chain crystalline block copolymers (SCCBC) which are a block copolymer consisting of both long alkane chains and functional units [24]. The surface modification mechanism is showed in Figure 1.…”

Ultra-high-molecular-weight polyethylene (UHMWPE) has been widely used in industry; however, the applications for UHMWPE are limited because of low hydrophilic and adhesive properties. Herein, we developed the surface properties of UHMWPE by using side-chain crystalline block copolymers (SCCBCs), which consist of a side-chain crystalline unit and a functional unit. This process only required immersing the UHMWPE film in the diluted SCCBC solution, which enabled the UHMWPE surface to be coated homogeneously. The results of the contact angle and tensile shear test showed that the surface of UHMWPE modified with SCCBC was improved in hydrophilicity and adhesive properties. In addition, high adhesion strength was measured on UHMWPE surfaces dipped in a SCCBC solution at high temperature with the UHMWPE film becoming elongated at all parts other than the adhesion contact area.

“…We have also found that this block copolymer interacts with polyethylene (PE) by crystalline supramolecular interaction and that it shows a strong adhesive interaction with PE. This block copolymer, in particular, exerts a very remarkable dispersant effect for a concentrated PE particle dispersion [10][11][12][13][14][15][16][17][18][19][20]. In this study, we have investigated the influence of the addition of this block copolymer on the crystallization of model wax/oil mixtures, and the temperature dependence on its rheological properties.…”

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.
