    • Disclosed herein are novel block polymers comprising at least one first block and at least one second block, wherein the at least one first block comprises at least one acrylate monomer of formula CH2═CH—COOR2 wherein R2 is chosen from C4 to C12 cycloalkyl groups and at least one methacrylate monomer of formula CH2═C(CH3)—COOR′2 wherein R′2 is chosen from C4 to C12 cycloalkyl groups, and the second block comprises at least one acrylic acid monomer and at least one monomer with a glass transition temperature of less than or equal to 20° C. Also disclosed herein is a process for the preparation of such polymers which may be carried out continuously in a single reactor. Finally, further disclosed herein are compositions comprising the novel polymers and processes using the composition for making up and/or caring for keratinous substances or for improving the hold of a cosmetic composition while maintaining its gloss.
    • 本文公开了包含至少一个第一嵌段和至少一个第二嵌段的新型嵌段聚合物,其中所述至少一个第一嵌段包含至少一种式CH 2 -CH 2 CO- 其中R 2 2选自C 4〜C 12环烷基和至少一个式CH的亚甲基双环[SUB 其中R'2选自C 4 - (CH 3) - COOR'2,其中R'2 < / SUB>至C 12环烷基,并且第二嵌段包含至少一种丙烯酸单体和至少一种玻璃化转变温度低于或等于20℃的单体。本文还公开 是制备这种聚合物的方法,其可以在单个反应器中连续进行。 最后,本文进一步公开的是包含新型聚合物和使用该组合物用于组合和/或关心角质物质或改善化妆品组合物的保持性同时保持其光泽的组合物。
