    • The invention pertains to a new method for formulating active fragrance ingredients in such a way as to protect them and to slow the evaporation method of said active ingredients. It relies upon the use of thickening acrylic emulsions, at a pH above 5 and containing hydrophobic groups in order to trap said active ingredients. The invention also pertains to various methods of realizing the active ingredients thus formulated: a mixture in water of these active ingredients with thickening emulsions, dispersion of solid particles of these polymers and of these active ingredients after acidification, and solid particles obtained in a dry state after water is eliminated. Finally, the invention pertains to the use of these various formulations in order to protect an active ingredient and slow its evaporation kinetic.
    • 本发明涉及一种以保护它们并减缓所述活性成分的蒸发方法的方式配制活性香料成分的新方法。 它依赖于使用增稠丙烯酸乳液,pH高于5,并含有疏水基团以捕获所述活性成分。 本发明还涉及实现如此配制的活性成分的各种方法:这些活性成分的水中的增稠乳液,这些聚合物的固体颗粒和这些活性成分在酸化后的分散体以及在干燥状态下获得的固体颗粒 水消除后。 最后,本发明涉及这些各种制剂的用途以保护活性成分并减缓其蒸发动力学。

    • Process for the preparation of impact-strengthened cast PMMA sheets comprising the following stages: 1. a mixture comprising: at least one alkoxyamine Z(-T)n, in which Z denotes a polyvalent group and n an integer greater than 2, preferably of between 2 and 10, advantageously between 2 and 8, and the monomer(s) intended to form a central block B is heated to a temperature sufficient to activate the alkoxyamine and polymerize the monomer(s); 2. the central block B, optionally mixed with the unconsumed monomer(s) from stage 1, is reactivated in the presence of the monomer(s) intended to form the branches A; 3. MAM and optionally at least one comonomer M which can be copolymerized by the radical route with MMA and at least one radical initiator are added to the mixture obtained in stage 2; 4. the mixture from stage 3 is cast in a mould and then heated.
    • 包括以下步骤的冲击强化流延PMMA片材的制备方法:1.一种混合物,其包含:至少一种烷氧基胺Z(-T)n,其中Z表示多价基团,n大于2,优选为 在2和10之间,有利地在2和8之间,并且旨在形成中心嵌段B的单体被加热到足以活化烷氧基胺并聚合单体的温度; 任选地与来自阶段1的未消耗单体混合的中心嵌段B在预期形成分支A的单体存在下再活化; 将可通过自由基途径与MMA和至少一种自由基引发剂共聚的MAM和任选的至少一种共聚单体M加入到阶段2中获得的混合物中; 将来自阶段3的混合物浇铸在模具中,然后加热。
