    摘要: A copolymer obtained by polymerizing two or more types of monomers, wherein among fractions obtained by dividing an eluate showing peaks relative to the copolymer, in an elution curve obtained by gel permeation chromatography (GPC), into eight fractions in order of fractionation, such that each fraction has the same volume, a difference between a monomer composition ratio of a copolymer contained in a first eluted fraction and a monomer composition ratio of all copolymers is −3 mol % to +3 mol % in any of the constitutional units derived from the respective monomers.

    摘要: The present invention relates to a process for the production of propylene copolymers wherein in a first step an olefin polymerisation catalyst comprising a solid catalyst component is subjected to a prepolymerisation reaction in a prepolymerisation reactor, in which propylene monomers are present in an amount of 98.0 to 99.9 mol % and further alpha-olefin monomers other than propylene are present in an amount of 0.1 to 2.0 mol %, based on the combined amount of propylene and further alpha-olefin monomers, so that a prepolymer is produced on the catalyst in an amount of 10 to 1000 g per g of the solid catalyst component, and in a second, subsequent step propylene and further alpha-olefin monomers other than propylene are copolymerised in the presence of the prepolymerised catalyst produced in the first step so that a propylene copolymer is obtained which contains at least 0.1 mol % of alpha-olefin units other than propylene, to propylene copolymers obtainable by such a process and to the use of a prepolymerised catalyst in such a process.
