This study aims to investigate the effects of methacrylate‐functionalized polyhedral oligomeric silsesquioxane (MA‐POSS) on polyolefin‐based adhesives. The so called adhesive was synthesized by the cooligomerization of 1‐decene/9‐decene‐1‐ol monomers using a Ti amine bis‐phenolate catalyst, [Ti{2,2′‐(OC6H2‐4,6‐tBu2)2NHC2H4NH(OiPr)2], which was subsequentlyacrylated via a simple reaction with methacryloyl chloride. Different weight fractions of MA‐POSS nanoparticles were solution blended with synthesized adhesive and undergone curing reaction with blue light. Observation of a unique tan δ peak in dynamic mechanical thermal analysis (DMTA) curve was clear evidence that two employed moieties were miscible and only one hybrid polymeric phase was created. Most noticeably, significant increase in mechanical parameters was detected in the lower inclusion compositions, 0.2‐1 wt% of MA‐POSS, where flexural strength and flexural modulus were increased up to 99 and 110%, respectively. Furthermore, thermal stability of the synthesized nanocomposite enhanced dramatically by increasing MA‐POSS weight fraction. Influence of employed nanoparticles on adhesion properties of synthesized nanocomposites was evaluated with tensile shear bond strength and pull off analysis. According to the adhesion results, the MA‐POSS causes an adhesion promotion on the fabricated adhesive/POSS nanocomposites.

甲基丙烯酸酯官能化的POSS可作为烯烃基胶粘剂的有效粘合促进剂
本研究旨在研究甲基丙烯酸酯官能化的多面体低聚倍半硅氧烷（MA-POSS）对聚烯烃基胶粘剂的影响。（OC -即所谓的粘合剂是通过使用钛胺双-酚盐催化剂，钛[Ti {2,2'的1-癸烯/ -9-癸烯-1-醇单体的合成cooligomerization 6 ħ 2 -4,6-吨Bu 2）2 NHC 2 H 4 NH（O i Pr）2然后通过与甲基丙烯酰氯的简单反应将其丙烯酸化。将MA-POSS纳米颗粒的不同重量分数与合成粘合剂溶液混合，并在蓝光下进行固化反应。在动态机械热分析（DMTA）曲线中观察到一个独特的tanδ峰，清楚地证明了所用的两个部分是可混溶的，并且仅产生了一个杂化聚合物相。最值得注意的是，在较低夹杂物成分（MA-POSS的0.2-1 wt％）中检测到机械参数的显着增加，其中弯曲强度和弯曲模量分别提高到99％和110％。此外，通过增加MA-POSS重量分数，可以大大提高合成纳米复合材料的热稳定性。通过拉伸剪切粘合强度和拉断分析评估了所用纳米颗粒对合成纳米复合材料粘合性能的影响。根据附着力结果，MA‐POSS会促进所制造的粘合剂/ POSS纳米复合材料的附着力。
