Cyclo-hexyl methacrylate

Reactive acrylic adhesives (sometimes called tough acrylics, reactive fluids, second-generation acrylics or methyl methacrylate adhesives are based on acrylate and methacrylate monomers, and have been used commercially for >50 years. Reactive acrylic adhesives are based on acrylic and methacrylic monomers, and polymerise via a free-radical route similar to catalysed anaerobic adhesives. However, very significant differences exist. Whereas the monomers in anaerobics are predominantly difunctional or trifunctional to achieve highly crosslinked thermoset systems, reactive acrylics are based mainly on monofunctional monomers e.g., methyl methacrylate, or cyclo hexyl methacrylate ... 

A flask was charged with 1-(1,1-dimethyl-2,2-ditrifluoromethyl-2-hydroxyl)ethyl methacrylate (176.46 g), l-(l-cyclohexyl-2,2-ditrifluoromethyl-2-hydroxyl)ethyl methacrylate (23.54 g), dimethyl 2,2 -azobisisobutyrate (3.74 g), and isopropyl alcohol (100.0 g) and then cooled to 20-25°C. In a separate flask isopropyl alcohol (50.0 g) was heated to 80°C and then added dropwise to the monomer solution over 4 hours and then stirred for 3 hours at 80°C. The solution was then cooled to ambient temperature and then precipitated in 4 liters of water and then isolated. The copolymer was washed four times with 600 g of isopropyl ether/hexane, 9 1, respectively, and a white solid isolated. After vacuum drying 90.1 g of the product was isolated having an Mw of 9600Da with a polydispersity of 1.6 and consisting of 80/20mol% 1-(l,l-dimethyl-2,2-ditrifluoromethyl-2-hydroxyl) ethyl methacrylate and l-(l-cyclo-hexyl-2,2-ditrifluoromethyl-2-hydroxyl)ethyl methacrylate, respectively.

Time of flight static secondary ion mass spectroscopy (SSIMS) has been applied to perfluorinated polymers, polystyrene, polyacylacrylates (including poly cyclo-hexylmethacrylate, polybenzyl methacrylate, polyphenyl methacrylate, poly n-hexyl methacrylate, poly n-butyl methacrylate, polymethylmethacrylate, poly n-propyl methacrylate, polyisopropyl methacrylate and poly secbutyl methacrylate). Blends of polystyrene and polyvinyl chloride, bisphenol A and polystyrene, polycarbonate and polystyrene and tetramethyl bisphenol A and polycarbonate have also been studied by this technique.
