Merschichtiges Elastomermaterial mit einem chemischen Wirkstoff und dessen Anwendungen

摘要

Multilayer elastomeric material comprises a middle layer L 2 comprising an elastomeric matrix containing dispersed droplets of a composition containing an active substance sandwiched between outer barrier layers L 1 and L 3, where the product of the breaking stress and thickness of L 2 is less than those of L 1 and L 3.
