Computational modeling of heterogeneous Ziegler-Natta catalysts for olefins polymerization

Single‐phase photo‐cross‐linkable adhesive synthesized from methacrylic acid‐grafted 1‐decene/9‐decene‐1‐ol cooligomer

“…[1,2] In the past 10 years, oligomers with relatively narrow polydispersities by different polar groups have been produced. [3,4] In this line, a number of methods for copolymerizing polar vinyl monomers with nonpolar olefin monomers have been studied. [5][6][7][8][9][10][11][12][13] Aforementioned copolymers/cooligomers have applications in industries such as clean diesel fuel alkanes, [14] octane boosters and new monomers, [15] adhesives, [16,17] compatilizers [18,19] synthetic lubricants, [20][21][22][23] additives for fuels [20] or in the paper, and leather industries.…”

Highly efficient supported AlCl3‐based cationic catalysts to produce polyα‐olefin oil base stocks

“…The most studied method of preparing immobilized AlCl 3 catalyst is the chlorination of Al 2 O 3 by chlorine‐containing compounds such as CCl 4 , CHCl 3 , and CH 2 Cl 2 in the polymerization of 4‐methyl‐1‐pentene, the copolymerization of propylene and butane, and the polymerization of isobutene . Notably, supported catalysts on γ‐Al 2 O 3 , which is thermally resistant with a high amount of Lewis acid sites, have also been reported . The foresaid catalysts are classified in the category of the heterogeneous acid catalysts.…”

“…[11][12][13] Notably, supported catalysts on γ-Al 2 O 3 , which is thermally resistant with a high amount of Lewis acid sites, have also been reported. [14,15] The foresaid catalysts are classified in the category of the heterogeneous acid catalysts. According to the determined mechanism [16] for oligomerization of olefins with heterogeneous acid catalysts, the reaction is initiated when olefin molecules are transformed to carbenium ions on Brønsted acid sites and further combine with olefin molecules in the bulk solution to form larger molecules.…”

Methacrylate‐functionalized POSS as an efficient adhesion promoter in olefin‐based adhesives

“…Polyolefins exhibit excellent properties in wide range of applications; however, the knowledge of their adhesion characteristics which is very crucial for many uses are limited. [1] Low surface adhesion results a serious problem in applications where other laminates, films, or metallic layers are imparted onto polyolefins. The surface modification of polyolefin is essential to increase adhesion properties.…”
