摘要:
Strippable systems comprising at least one pressure sensitive adhesive based on at least one block copolymer, wherein said at least one block copolymer is based at least in part on (meth)acrylic acid derivatives, the block copolymers containing at least the unit P(A)-P(B)-P(A) composed of at least one polymer block P(B) and at least two polymer blocks P(A), where P(A) independently of one another represent homopolymer or copolymer blocks of monomers A, the polymer blocks P(A) each having a softening temperature in the range from +20° C. to +175° C., P(B) represents a homopolymer or copolymer block of monomers B, the polymer block P(B) having a softening temperature in the range from −100° C. to +10° C., and the polymer blocks P(A) and P(B) are not homogeneously miscible with one another.
