    摘要: The present invention relates to polypropylene impact copolymer compositions which exhibit improved stiffness without degrading the impact resistance performance. The polypropylene impact copolymer comprises a matrix and a dispersed phase. The matrix comprises a polypropylene homopolymer or a propylene/alpha-olefin random copolymer which comprises more than 50 wt. % of units derived from propylene monomer. The matrix should have a relatively high crystallinity, preferably 50% or greater. The polypropylene homopolymer or a propylene/alpha-olefin random copolymer preferably has a MWD between 4 and 8, such as typically obtained using Ziegler-Natta catalysts. The dispersed phase in the impact copolymer comprises an ethylene-propylene copolymer which comprises from 45 to 70 wt. % of units derived from an ethylene monomer. Preferably the dispersed phase comprises from 20 to 50 percent by weight of the polypropylene impact copolymer.

    摘要: This invention relates to a polymer foam prepared by dispersing an organophilic multi-layered material into a melt comprising an olefinic or styrenic polymer having polar functionality so that at least a portion of the polymer intercalates between layers of the particles; and expanding the polymer with a blowing agent under such condition to form the polymer foam. The organophilic multi-layered material can also be dispersed into an olefinic or styrenic monomer, which can then be polymerized to form a polymer melt prior to, or along with the foaming step.
