摘　　要：SEBS是PET、PC、PA等极性树脂材料的增韧改性剂,然而SEBS是非极性材料,与极性树脂材料相容性差,单纯的熔融共混得不到理想的分散效果,进而阻碍了材料性能的提升。针对这一问题,在SBS聚合末期,使用环氧乙烷对其进行封端,制备末端官能化SBS-OH,随后在催化剂作用下对SBS-OH进行选择性加氢,GPC和~1H-NMR证明成功合成SEBS-OH。TGA测试表明所制备的末端官能化SEBS材料具有较好的热稳定性。SEBS is a toughening modifier for polar resin materials such as PP and PC.However,SEBS is a non-polar material with poor compatibility with polar resin materials.Pure melt blending cannot achieve ideal dispersion effect,which hinders the improvement of material properties.In response to this issue,in the final stage of SBS polymerization,a chemical reaction was carried out using ethylene oxide and SBS and prepared end functionalized SBS-OH.Subsequently,SBS-OH was selectively hydrogenated under the action of a catalyst,and GPC and 1H-NMR confirmed the successful synthesis of SEBS-OH.The contact angle and TGA tests indicate that the end functionalized SEBS material prepared has good hydrophobicity and thermal stability.
