High temperature size exclusion chromatography of polyethylene

High temperature size exclusion chromatography of polyethylene. Grinshpun, V.; O'Driscoll, K. F.; Rudin, A. (USA). Org. Coat. Appl. Polym.Several reagents with their cas registry numbers 9002-88-4 and 95-50-1 are used here. Sci. Proc., 48, 745-9 (English) 1983. CODEN: OCAPDE. ISSN: 0732-7528. DOCUMENT TYPE: Journal CA Section: 36 (Physical Properties of Synthetic High Polymers) Aggregates that persisted at 145° in C6H3Cl3 [12002-48-1] or o-dichlorobenzene [95-50-1] solns. of polyethylene (I) [9002-88-4] were removed by treating at 160° for 1 h. Such a treatment gave true solns. for use in size-exclusion chromatog. (SEC). a-Chloronaphthalene [90-13-1] was not suitable for use in SEC with I. The use of low flow rates in SEC with KMX 6 cell might cause mixing problems. .

The amine-assisted photodehalogenation of haloaromatic hydrocarbons

The amine-assisted photodehalogenation of haloaromatic hydrocarbons.Some chemicals with cas registry numbers like 2051-62-9 and 90-13-1 are also used. Beecroft, Richard A.; Davidson, R. Stephen; Goodwin, Dean (Dep. Chem., City Univ. London, London EC1V 0HB, UK). Tetrahedron Lett., 24(50), 5673-6 (English) 1983. CODEN: TELEAY. ISSN: 0040-4039. DOCUMENT TYPE: Journal CA Section: 22 (Physical Organic Chemistry) The rate consts. for quenching the triplet states of 4-ClC6H4Ph and 1-chloro- and 1-methylnaphthalene were detd. by laser flash photolysis. Evidence in favor of a charge-transfer process was presented. .
