  • Poly(1-butene)resin composition
    Patent number: 5221715
    Abstract: The composition of this invention is a poly(1-butene) resin composition which has characteristics such as excellent rigidity, creep characteristic and impact resistance, which a poly(1-butene) resin inherently possess, and is excellent in moldability, particularly moldability in high molding speed, so-called high speed moldability. This composition is particularly useful in the manufacture of hot water pipes.
