Abstract
A composition based on triblock copolymers of the ABA type, including two styrene thermoplastic terminal blocks A, glassy at use temperature, and an elastomeric central block B which is a saturated olefin, at least one linear polymer of the polyisobutene type having a very low molecular weight and specific crosslinked polymer particles. The composition exhibits advantageous adhesion and holding properties on the skin which are similar to the properties obtained by matrices based on silicone elastomers. They also exhibit particularly interesting cohesion.
