An information processing method executed by one or more processors included in an information processing apparatus. The method includes obtaining a notice indicating that a deferred payment has been selected for a settlement of a price of a product on a website; identifying a seller to which the settlement is to be made; receiving a request for settlement on an amount of money determined based on information including information on delivery of the product and information on the price of the product; and advancing the settlement in a case where the amount of money is less than or equal to an upper limit of an amount of settlement using the deferred payment allowed for a user.

Information processing method, information processing apparatus, and program

A process for producing an olefin polymer with high polymerization activity without using an expensive co-catalyst or using a limited amount of the co-catalyst, more particularly a process for producing a high molecular weight (co)polymer with high polymerization activity even at a high polymerization temperature which is more practical. At least one olefin is polymerized by means of a polymerization catalyst comprising at least one transition metal compound selected from transition metal compounds which have a substituted indenyl group, represented by a certain specific chemical formula, and an organoaluminum compound represented by the formula Al(R).

Process for producing polymer

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.

Process for producing olefin/aromatic vinyl copolymer

A transition metal catalyst component for polymerization, composed of a metal complex comprising specific ligands and a specific substituted boron group and having a bridging group, which exhibits a very high activity for an olefin type (co)polymerization or an olefin-aromatic vinyl compound copolymerization, whereby the molecular weight of a copolymer obtainable, is high. A method for producing an olefin (co)polymer and an aromatic vinyl compound-olefin copolymer, by means thereof.
