PURPOSE:The titled composition, consisting essentially of a vinyl chloride based polymer containing a specific stabilizer added thereto during polymerization, partially crosslinked acrylonitrile-butadiene copolymer and plasticizer, and having improved heat and weather resistance and nonmigration property and shape retaining property at high temperatures and compression set characteristics. CONSTITUTION:A thermoplastic elastomer composition obtained by incorporating (A) 100pts.wt. high polymer consisting of (A) 80-40wt% vinyl chloride based polymer, prepared by adding 0.1-10pts.wt. N-(3-methacryloyloxy-2-hydroxypropyl)-N'-phenyl-p-phenylenediamine to 100pts.wt. vinyl chloride monomer or 100pts. wt. mixture thereof with vinyl based monomer copolymerizable therewith, e.g. ethylene or vinyl acetate during polymerization, and having >=2,000 average polymerization degree and (B) 20-60wt% partially crosslinked acrylonitrile- butadiene copolymer with (C) 20-200pts.wt. plasticizer.
