Abstract: The prepn. of monovinyl ethers of formula (I), comprises reacting a diol of formula (II) with C2H2 in the presence of a base. The reaction is carried out at 150-250 degrees C and an C2H2 partial pressure of 5-25 bar until the diol conversion is 40-80%, then the reaction is stopped and (I) is isolated. In (I) and (II): A = a chemical bond, -CH2- or -CH2CH2-; R , R = H, (cyclo)alkyl or aryl; or R R = a 3-5C alkylene bridge.

Abstract: Prepn. of N-vinyl-lactams (I) of formula (A) (where R = CH=CH2; n=1-3) comprises reacting lactams (II) of formula (A) (where R = H; n = 1-3) with (a) 10-90 wt.% aq. alkali hydroxide soln. by distn. at 50-250 degrees C and 1-100 mbar with a residence time of 0.1-5 hrs. and then (b) C2H2 at 60-250 degrees C and 1-100 bar. Pref. reaction (a) is carried out in a column with at least 2 theoretical plates. (II) and aq. alkali hydroxide soln. are fed into the upper third of the column. A 30-60, esp. 45-55 wt.% soln., more esp. KOH soln., is used. Reaction is carried out at 70-180 degrees C and 1-30 mbar with a residence time of 0.5-2 hrs.

Date Mar. 2, 1995Water-soluble copolymerizates are disclosed containing carboxyl groups, and also containing the following components incorporated by polymerization: (a) 30 to 80 mol % monoethylenically unsaturated C3-C8 carboxylic acids, anhydrides thereof and/or water-soluble salts thereof; (b) 10 to 50 mol % C2-C8 olefines, styrene, alkyl styrene, C1-C10 alkyl vinyl ethers and/or vinyl esters of saturated C1-C10 monocarboxylic acids; and (c) 0.01 to 20 mol % vinyl ethers and/or allyl ethers of alkoxylated C1-C30 alcohols. The copolymerizates in question have a K-value of at least 8 (determined after H. Fikentscher). Also disclosed are methods of producing the water-soluble copolymerizates by copolymerization of the monomers in the presence of radical-forming polymerization initiators, and the use of the polymerizates as scale inhibitors.
