Abstract: The acrolein polymer is characterised by the physicochemical data: Weight average wherein ni means number of mol and Mi means molecular weight Mw: 2000 - 6000 D Carbonyl content: 0.5 - 5 mol/kg of polymer It is produced by simultaneously adding acrolein and catalyst to a reaction medium in a vessel in such a manner that the temperature of the reaction medium does not exceed 25.degree.C and the pH value of the reaction medium is 10 to 11, the mixture is stirred on completion of addition and the acrolein polymer separated. The acrolein polymer is used in biocidal agents.

Abstract: The invention relates to an improved process for preparing triallyl cyanurate (TAC) by reacting cyanuric chloride with allyl alcohol in the presence of an alkali metal acid acceptor and in the absence of an organic solvent other than allyl alcohol. According to the invention, TAC is obtained in over 99% purity with an APHA colour number below 10 in a yield of over 90% when 3.9 to 6.0 mol of allyl alcohol and 3.0 to 3.2 equivalents of acid acceptor are used per mole of cyanuric chloride, cyanuric chloride and acid acceptor are added simultaneously or successively to anhydrous or at least 50% by weight aqueous allyl alcohol, and the reaction is performed in one or more stages at a temperature in the range of -5 to +50°C.
