2-(Meth)acrylamido-2-methylpropanephosphonic acid is prepared by reaction of 2-methylprop-1-ene-1-phosphonic acid or 2-methylpro-2-ene-1-phosphonic acid with (meth)acrylonitrile in the presence of an equimolar amount of a strong acid. The compounds are suitable as such or in the form of their salts as comonomer for the manufacture of copolymers, which are used inter alia as dyeing auxiliaries and as scale inhibitors.
2-(甲基)丙烯酰胺基-2-甲基丙烷磷酸是通过2-甲基丙烯基-1-磷酸或2-甲基丙烯-1-磷酸与(甲基)丙烯腈在强酸的等摩尔量存在下反应制备的。这些化合物适用于作为共聚物的共聚单体,可以直接使用或以盐的形式使用,用于制造用途,例如作为染料助剂和阻垢剂。
