摘要： A multilayer pressure-sensitive adhesive foam tape that includes: a pressure-sensitive adhesive polymeric foam layer having a first major surface and a second major surface, wherein the polymeric foam comprises: a poly(meth)acrylate derived from a (meth)acrylate-based (co)polymer component having a weight-average molecular weight (M w ) no greater than 500,000 g/mol and comprising at least one reactive functional group (X); and an optional additive selected from the group consisting of a density-reducing solid filler, a tackifier, a VOC scavenger, an odor absorber (particularly, activated carbon), a stabilizer, a rheological modifier, a thixotropic compound, and a combination thereof; a first pressure-sensitive adhesive skin layer adjacent the first major surface of the foam layer; and a second pressure-sensitive adhesive skin layer adjacent the second major surface of the foam layer.

摘要： The present disclosure relates to a precursor composition of a pressure sensitive adhesive comprising:
a) a (co)polymeric base component having a weight-average molecular weight (M w ) no greater than 500.000 g/mol and comprising at least one reactive functional group (X); and
b) a multi-functional oligomeric branching compound comprising an oligomer backbone and having a weight-average molecular weight (M w ) greater than 250 g/mol, wherein the multi-functional oligomeric branching compound comprises at least two complementary reactive functional groups (Y) which are capable of chemically reacting with the at least one reactive functional group (X) of the (co)polymeric base component.

摘要： The present disclosure relates to a multilayer construction which comprises:
a) at least one layer of a precursor of a pressure sensitive adhesive composition comprising a radiation-curable (co)polymeric base component having a weight-average molecular weight (M w ) no greater than 500.000 g/mol;
b) at least one constraining layer; and
c) optionally, at least one spacer layer.
