    • In a first step of this process an elastomer latex is prepared in aqueous emulsion in the presence of at least one ionic surfactant and at least one ethylenically unsaturated monomer; then in a second step at least one vinyl monomer, which is insoluble in water or sparingly soluble in water, is added to the latex thus obtained and the ionic charges introduced by the said latex are neutralised by adding to the mixture of latex and monomer at least one transfer agent carrying ionic charges opposite to those of the surfactant used in the first step, in order to effect the transfer of particles of the latex into the vinyl monomer; then in a third step the aqueous phase is separated from the organic phase comprising the latex and the vinyl monomer; and in a fourth step the bulk polymerisation of the organic phase is carried out in such a way as to obtain the cast sheet after cooling and release from the mould.
    • 在该方法的第一步中,在至少一种离子表面活性剂和至少一种烯键式不饱和单体的存在下,在水乳液中制备弹性体胶乳; 然后在第二步骤中,将至少一种不溶于水或微溶于水的乙烯基单体加入到由此获得的胶乳中,由所述胶乳引入的离子电荷通过向胶乳和单体的混合物中加入 至少一个转运剂携带与第一步骤中使用的表面活性剂相反的离子电荷,以实现将胶乳颗粒转移到乙烯基单体中; 然后在第三步骤中,将水相与包含胶乳和乙烯基单体的有机相分离; 并且在第四步中,有机相的本体聚合以这样的方式进行,以便在冷却和从模具中释放之后获得流延片。
