    摘要: A highly uniform vinyl compound polymer-cross-copolymerized olefin/styrene/diene copolymer excellent in processability, mechanical properties, high temperature properties, compatibility and transparency, and its composition and a process for its production, are provided. This copolymer is a crossed polymer obtained by cross-copolymerizing an olefin/styrene/diene copolymer having a styrene content of from 0.03 mol % to 96 mol %, a diene content of from 0.0001 mol % to 3 mol % and the rest being an olefin, with an olefin/aromatic vinyl compound copolymer.

    摘要: An olefin/aromatic vinyl compound copolymer which is excellent in transparency and which satisfies flexibility and heat resistance simultaneously can be produced by carrying out polymerization in such a manner that at least one of conditions: (a) the polymerization is carried out to an aromatic vinyl compound monomer conversion ratio of at least 50 mol % when the polymerization is completed, and (b) the polymer concentration is at least 10 mass % relative to the polymerization solution when the polymerization is completed, is satisfied, and the olefin partial pressure is changed so that the olefin partial pressure when the polymerization is completed is from 1.3 to 20 times the olefin partial pressure at the initiation of the polymerization.

    摘要: To provide a novel cross copolymer and resin composition which are improved in heat resistance and compatibility over conventional ethylene/aromatic vinyl compound copolymers and which have low crystallinity, are excellent in softness, transparency and compatibility and show mechanical properties similar to soft vinyl chloride resins, as compared with conventional cross copolymers.A process for producing a cross copolymer, which comprises a coordination polymerization step and a subsequent anionic polymerization step, wherein in the coordination polymerization step, copolymerization of an olefin monomer, an aromatic vinyl compound monomer and an aromatic polyene is carried out by using a single-site coordination polymerization catalyst to synthesize an olefin/aromatic vinyl compound/aromatic polyene copolymer, and then, in the anionic polymerization step, polymerization is carried out in the coexistence of such an olefin/aromatic vinyl compound/aromatic polyene copolymer and an anionic polymerizable vinyl compound monomer by using an anionic polymerization initiator.
