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.
