| 摘要 |
A masterbatch usable for producing manufactured articles made of expanded aromatic polyester resin, comprising an elastomeric material selected among an ethylene/acrylic ester/third monomer terpolymer, where the acrylic ester radical is an alkyl or isoalkyl containing 1 to 6 carbon atoms, while the third monomer is maleic anhydride or glycidyl methacrylate or mixtures thereof, and an ethylene-alkyl or isoalkyl acrylate copolymer as defined above, linked with maleic anhydride or glycidyl methacrylate or mixtures thereof, wherein a polyfunctional compound is dispersed in the elastomeric material and is selected among dianhydrides of tetracarboxylic, aromatic or aliphatic acids and polyepoxy compounds.
