Chemistry is traditionally divided into organic and inorganic chemistry. The former is the study of compounds containing at least one carbon-hydrogen bonds. 91526-18-0, Name is 4-(Hydroxymethyl)-5-methyl-1,3-dioxol-2-one, molecular formula is C5H6O4, belongs to dioxoles compound, is a common compound. In a patnet, author is Forsythe, JS, once mentioned the new application about 91526-18-0, Recommanded Product: 91526-18-0.
The radiation chemistry of the copolymer of tetrafluoroethylene with 2,2-bis(trifluoromethyl)-4,5-difluoro-1,3-dioxole
The radiation chemistry of the copolymer of tetrafluoroethylene and 2,2-bis(trifluoromethyl)-4,5-difluoro-1,3-dioxole (Teflon AF(R)) was investigated using gamma-irradiation under vacuum. Two types of resin were studied which differed in dioxole content; AF1600 65 mol% dioxole and AF2400 87 mol% dioxole. The cyclic fluoroplastic was found to undergo predominant main chain scission upon radiolysis, both above and below the glass transition temperature, which was characterised by a decrease in the glass transition temperature. FTIR analysis showed the formation of new carboxylate end groups as well as terminal unsaturation. Both CF . and CF2., radicals were identified using Electron Spin Resonance upon gamma-radiolysis and subsequent thermal annealing. The G-value for radical production at 77 K, G(R), was 1.6 for both resins. (C) 1998 Elsevier Science Ltd. All rights reserved.
