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′‐(OC 6 H 2 ‐4,6‐ t Bu 2 ) 2 NHC 2 H 4 NH(O i Pr) 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.
