Beschreibung
Zusammenfassung:	A foamable precursor of a microcellular foamed polymeric composition, wherein the foamable precursor comprises:a) the graft copolymerization reaction product of a copolymerizable monomer mixture comprising:i. at least one (meth)acrylate comonomer; andii. at least one copolymerizable macromonomer comprising an oligomeric backbone selected from the group consisting of thermoplastic oligomeric material having a Vicat softening temperature greater than 20°C, when measured according to test method ASTM D1525-09, wherein the copolymerizable macromonomer further comprises a copolymerizable ethylenically unsaturated functional group at one terminal position of the oligomeric backbone; andb) optionally, a physical foaming agent.
