    摘要： These processes are characterized (1) using two or more polymerizers connected in series; (2) supplying all of a catalyst and molecular weight regulator (hydrogen) to thefirst polymerizer; (3) removing gas from the second and/or subsequent (if any) polymerization at a rate of tanks being 0.5 to 10 V₁/Hr (V₁/Hr (V₁ being a volume of the polymerizer) calculated at NTP. In the process for producing the copolymer, monomers having an ethylene content of 5 wt.% or less are supplied to a first step carried out as described above; after which, in a subsequent polymerizer, monomers containing at least 10 wt.% ethylene are introduced and polymerized.

    摘要： A continuous multi-stage process for the production of a propylene-ethylene block copolymer comprises: (i) in a first polymerization stage, directed mainly to the polymerization of propylene, continuously polymerizing propylene, alone or in admixture with ethylene, in the presence of a stereoregular catalyst comprising (A) a titanium-containing solid catalyst component combined with (B) an organoaluminium compound of the formula Al(R²) m X 3-m (in which R² is a C₁-C₂₀ hydrocarbyl group, X is a halogen atom and m is a number from l.5 to 3), and an inert organic solvent or propylene as solvent; and (ii) in a second polymerization stage, continuously polymerizing ethylene, alone or in admixture with propylene, in the presence of the polymerization reaction mixture from the first stage after partial inactivation of the stereoregular catalyst; the first polymerization stage being carried out in two or more polymerization vessels connected in series and using a propylene/ethylene feed containing from 0 to 5% by weight of ethylene, based on the total of propylene and ethylene, to produce from 60 to 95% by weight of the final polymerization product;
    the stereoregular catalyst being partially inactivated by addition thereto of a glycol ether (C) in an amount such that the ratio (mole/atom) of moles of glycol to atoms of titanium in the stereoregular catalyst (A) is from 0.0l to l.0; and the second polymerization being carried out in one or more reaction vessels using an ethylene/propylene feed containing from l0 to l00% by weight of ethylene, based on the total weight of ethylene and propylene, to produce from 5 to 40% by weight of the final polymerization product.

    摘要： An ethylene-propylene block copolymer capable of producong foamed shaped articles with a uniform and fine foam structure even without adding resins comprises a propylene homopolymer portion and an ethylene-propylene (EP) copolymer portion and is characterised in that the homopolymer portion is obtained by polymerizing propylene in two stages so that the propylene homopolymer portion comprises a lower and a higher molecular weight portion, relative to the molecular weight of the propylene homopolymer portion; there is a specified relationship between the melt flow rates under defined conditions; the EP copolymer portion has an ethylene content of 60 to 95 % based on the copolymer portion; and the block copolymer has an ethylene content of 10 to 40 % based on the block copolymer.
