description

Die Copolymerisation des Acroleins in wasrigem Medium wird untersucht und die copolymerisationsparameter folgender Systeme bestimmt: Acrolein/Aacrylnitril (r1 = 1,09; r2 = 0,77); Acrolein/Acrylamid (r1 = 2,0; r2 = 0,76); Acrolein/Acrylsauremethylester (r1 = 0,2; r2 = 10,0) und Acrolein/Vinylacetat (r1 = 3,3; r2 = 0,1). Ferner werden die Qund e-Werte fur Acrolein berechet und sein Verhalten bei der Copolymerisation diskutiert. The copolymerisation of acrolein in aqueous medium has been investigated and the reactivity ratios of the following systems were determined: acrolein/acrylonitrile (r1 = 1.09; r2 = 0.77 ); acrolein/acrylamide (r1 = 2.0; r2 = 0.76); acrolein/methacrylate (r1 = 0.2; r2 = 10.0); acrolein/vinylacetate (r1 = 3.3; r2 = 0.1 ). Moreover the Q- and e-values were calculated for acrolein and its behaviour in copolymerisation is discussed.
