Title: REVERSIBLE PRESSURE-SENSITIVE ADHESIVE MASS
Abstract:
The invention relates to, among other things, pressure-sensitive adhesive masses. According to at least one embodiment, a pressure-sensitive adhesive mass comprises an at least partially cross-linked polyacrylate on the basis of a monomer mixture. The monomer mixture comprises: a) 5 to 100 wt% of acrylic acid esters of the formula CR3 2 = C(R2)(COOR1) as monomers A, wherein R1 is a branched alkyl group with 16 to 22 C atoms having at least two branching points, R2 is selected from H, methyl, or halogen, and R3 is selected from H or halogen, each selected independently from one another; b) 0 to 95 wt% of acrylic acid esters of the formula CR6 2 = C(R5)(COOR4) as monomers B, wherein R4 is a linear, mono-branched, cyclic or polycyclic alkyl group having 1 to 14 C atoms, R5 is selected from H, methyl, or halogen, and R6 is selected from H or halogen, each selected independently from one another; c) 0 to 5 wt% of monomers having at least one alcoholic hydroxyl group as monomers C; d) 0 to 5 wt% of monomers having at least one COOH-group as monomers D; e) 0 to 5 wt% of monomers having at least one epoxy group as monomers E, and f) 0 to 2.5 wt% of monomers having at least one UV-activatable group as monomers F.
