| 摘要 |
The invention relates to a multi-layer product, comprising at least one layer of an acrylate-based foam carrier (S); and a multi-phase polymer composition (P) applied to said layer; wherein the multi-phase polymer composition (P) comprises: a comb copolymer (A), which can be obtained by polymerizing at least one (meth)acrylate monomer in the presence of at least one macromer, selected from the group comprising polymerizable ethylene-butylene, ethylene-propylene, ethylene-butylene-propylene, and isobutylene macromers, and which forms a continuous acrylate phase and a discontinuous hydrocarbon phase Kw; and at least one hydrocarbon component (B) soluble in the hydrocarbon phase Kw of the comb copolymer (A), the at least one hydrocarbon component comprising at least one soft resin and at least one solid resin; wherein the multi-phase polymer composition (P) has a continuous acrylate phase having a static glass transition temperature Tg(Ac) measured according to the DSC method and a discontinuous hydrocarbon phase Kw1 containing the hydrocarbon component (B) and having a static glass transition temperature Tg(Kw1) measured according to the DSC method, and wherein Tg(Kw) is higher than Tg(Ac) by 35 to 60 kelvin, preferably by 40 to 60 kelvin, more preferably by 45 to 60 kelvin. The invention further relates to a method for producing the multi-layer product, to an adhesive tape comprising the multi-layer product, and to the use of the multi-layer product to adhesively bond objects. |
