  • Composition derived from a softening agent and a thermoplastic resin composition containing the same
    Patent number: 7528197
    Abstract: This invention provides a softening agent composition obtained by blending and heat treating (a) 100 parts by weight of at least one non-aromatic hydrocarbon softening agent for rubber; (b) 0.1 to 10 parts by weight of an organic peroxide; and (c) 0.1 to 50 parts by weight of a crosslinking aid, with the proviso that the weight ratio of component (b) to component (c) is 1 or less. The softening agent composition is useful and very easy to handle in the production of a thermoplastic resin composition.
    Type: Grant

  • Thermoplastic elastomer resin composition
    Patent number: 7030189
    Abstract: The present invention is a thermoplastic elastomer resin composition comprising (A) 50 to 90% by weight of a urethane-based thermoplastic elastomer; (B) 5 to 45% by weight of polar group-containing thermoplastic elastomer; and (C) 5 to 45% by weight of a thermoplastic elastomer, and a shaped article, which is excellent in moldability, oil resistance scratch and softness.
