  • 4-METHYL-1-PENTENE BASED RESIN FOAM AND METHOD FOR PRODUCING SAME
    Publication number: 20220235157
    Abstract: 4-methyl-1-pentene based resin foam containing a 4-methyl-1-pentene based resin, and having an expansion ratio of 3 times or more is prepared. When measured in a decalin solvent at 135° C., an intrinsic viscosity [?] of the 4-methyl-1-pentene based resin may be 0.5 to 5 dl/g. The 4-methyl-1-pentene based resin may have a glass transition temperature of 0° C. to 80° C. The 4-methyl-1-pentene based resin may have a melting point. The 4-methyl-1-pentene based resin may be a 4-methyl-1-pentene/C2-20?-olefin copolymer (in particular, 4-methyl-1-pentene/C2-4?-olefin copolymer). The expansion ratio of the 4-methyl-1-pentene based resin foam may be 10 times or greater.
