    Abstract: A polymer has a betaine structure on at least one lateral chain, and is suitable as a material for manufacturing a pervaporation membrane. Also described is a process for manufacturing said polymer, in which betaine groups are introduced in an initial polymer. This is performed by irradiating the initial polymer with ionizing radiation and treating the latter with monomers able to effect a graft reaction. Use is made of monomers which either already contain a betaine function or are capable of forming one. The betaine formation can, for example, be effected by alkylizing quaternization of a neutrogen atom contained in the monomer if an acid group is simultaneously introduced with the alkylizing medium.

    Abstract translation: 聚合物在至少一个侧链上具有甜菜碱结构,并且适合作为用于制造渗透蒸发膜的材料。 还描述了一种制备所述聚合物的方法,其中甜菜碱基团被引入初始聚合物中。 这是通过用电离辐射照射初始聚合物并用能够进行接枝反应的单体处理后者来进行的。 使用的是已经含有甜菜碱功能或能形成甜菜碱功能的单体。 如果酸基与烷基化介质同时引入,则甜菜碱形成可以例如通过烷基化单体中所含的中性原子的季铵化来实现。

    Abstract: In order to produce solution diffusion membranes, homogeneous and dense films produced by extrusion of melted material or by molding from synthetic polymers having a melting temperature higher than 140 C, a vitreous transition temperature higher than 0 C and a permanent stability in the presence of boiling ethanol are irradiated by accelerated electrons and are subjected to a graft curing of radicals with monomers containing functional groups. After said curing, the functional groups of grafted polymers are converted into dissociated salts.
