ABSTRACT:
There are disclosed a styrenic block copolymer having a reduced viscosity of 0.01 to 20 dl/g (0.05 g/l in 1,2,4-trichlorobenzene at 135.degree. C.) which comprises highly syndiotactic styrenic-polymer segments and 10.sup.-4 to 10 mol % of heteroatom-containing styrenic polymer segments; a resin composition comprising the above styrenic block copolymer and a thermoplastic resin, an inorganic filler or an organic filler; a multi-layer material comprising at least one layer composed of the above styrenic block copolymer or the above resin composition; and a process for producing the above styrenic block copolymer which comprises polymerizing a styrenic monomer in the presence of a specific catalyst and adding a heteroatom-containing styrenic monomer to successively proceed with copolymerization reaction. The above-disclosed styrenic block copolymer and the resin composition exhibit excellent compatibility and adhesivenesss, and the multi-layer material is expected to find a wide range of applications in automobile parts, electrical and electronic parts as well as film, sheet, etc.
