| 摘要 |
The invention relates to a pressure-sensitive adhesive. It is envisaged that this pressure-sensitive adhesive comprises at least 50% by weight of at least one block copolymer formed from a comonomer composition comprising acrylic acid derivatives or methacrylic acid derivatives, the block copolymer comprising a unit P(A)-P(B)-P(A) comprising a polymer block P(B) and two polymer blocks P(A); the polymer blocks P(A) independently of one another representing 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) representing a homopolymer or copolymer block of monomers B, the polymer block P(B) having a softening temperature in the range from -130° C. to +10° C.; and the polymer blocks P(A) and P(B) being not homogeneously miscible with one another.
