Hybrid polymer solutions were prepared using methacrylate-capped macromonomers, which contain essentially no strong acids or metal catalysts. The average molecular weight of the macromonomer was determined by the GP°C method using polystyrene as a standard substance, and the result was M6600, Mw=7200 Dalton. The initial addition mixture was prepared to contain 5973 g of 2-ethylhexyl […]
A typical acrylic pressure-sensitive adhesive is an alkyl ester monomer, a functional monomer such as acrylic acid. Copolymers can be cross-linked with, for example, aluminum chelators. These adhesives are generally deficient for low-energy surfaces. Lack of adhesion, but these adhesives can be improved by adding rosin esters to the low-energy surface it works. But at […]
Preparation of a parent-modified acrylate copolymer adhesive Preparation of amphiphilic oligomers 12g octadecyl alcohol, 7g maleic anhydride, and 65g xylene were mixed evenly and poured into a round-bottom flask; The monoester of octadecyl maleate was obtained at 120℃ for 4h. 10g octadecyl maleate, 7.5g polyethylene glycol 600, 1.6g p-toluene sulfonic acid, and 150g toluene was […]
Solution A is first prepared by mixing 44g deionized water with 0.25g polyoxyethylene nonyl ether sulfate (0NH4. Polyoxethyene Nonyl ether sulfate, China Japan Synthesis Company). In addition, 76.7g deionized water, 2.9g polyoxyethylene nonyl pheny1 ether, 12.9g polyoxyethylene nonyl pheny1 ammonium sulfate, 157.3g were obtained 2-ethylhexyl acrylate monomer, 102.6g dioctyl maleate monomer, 85.5g ethyl collate. The […]
