Abstract

An innovative approach for functionalization of polyolefins was developed and newfound polyolefins end-capped with trimethoxysilane (silylated polyolefins) was discovered as a material which can be applicable as an extraordinary polyolefin-based adhesive. For synthesizing mentioned materials, 1-octene as a higher α-olefin was cooligomerized with linear, non-conjugated (1,5-hexadine and 1,7-octadiene) by the metallocene catalyst system of Cp2HfCl2/MAO at room temperature. Then, amine-terminated trimethoxysilane (3-aminopropyltrimethoxy silane) in the presence of palladium(II) acetate was reacted with unsaturated bonds containing of synthesized cooligomers by nucleophilic addition. The adhesion properties of resultant adhesives were subjected to different substrates. Obtained adhesives indicated greater tendency to Al substrate. Furthermore, the tensile shear strength of the synthesized adhesives on polar substrates was 2.21% to 2.84% more than that on polar substrates.
