  • Polymer composition, foam and method thereof
    Patent number: 11746226
    Abstract: The present invention provides a polymer composition for manufacturing a foam, the polymer composition comprising a vinyl aromatic based copolymer and a processing aid, wherein the amount of the processing aid in the total weight of the polymer composition is equal to or more than 5 wt % and equal to or less than 75 wt %; and the polymer composition does not comprise ethylene-vinyl acetate copolymer, ethylene-butyl acrylate copolymer, ethylene-?-olefin copolymer, homopolymer and copolymer of polyethylene, homopolymer and copolymer of polypropylene, homopolymer and copolymer of polybutene and olefin-based ionic polymer. The present invention also provides the foam and the method for forming the same.
