Block polymers and cosmetic compositions and processes comprising them

摘要

The present invention relates to novel block polymers comprising at least one first block and at least one second block that are incompatible with each other, have different glass transition temperatures (Tg), and are linked together via an intermediate segment comprising at least one constituent monomer of the at least one first block and at least one constituent monomer of the at least one second block. The block polymer has a polydispersity index I of greater than 2. The invention also relates to cosmetic compositions comprising the block polymers and processes for their use.
