Abstract
A resin composition for a masterbatch of foaming agent, comprising: PA0 (A) 100 parts by weight of a resin component comprising PA1 (i) 100 to 20% by weight of a modified resin having an aromatic vinyl monomer unit content of 5 to 70% by weight, the aromatic vinyl monomer unit being obtained by subjecting an ethylene polymer resin or propylene polymer resin and an aromatic vinyl monomer to graft polymerization, and PA1 (ii) 0 to 80% by weight of an ethylene polymer resin or propylene polymer resin, and PA0 (B) 1 to 50 parts by weight of a chemical foaming agent.
