Patent number: 6841619Abstract: The present invention provides an olefin-based block copolymer that has an olefin block that is substantially saturated and at least one (poly)ester or (poly)ether block. The olefin-based block copolymer of the invention can be prepared by reacting a liquid hydroxyl-functional, saturated or substantially saturated olefin polymer with a chain-extension reagent that is reactive with hydroxyl groups and will polymerize in a head-to-tail arrangement of monomer units. The olefin-based block copolymer of the invention can be used to prepare an adhesion promoter that provides excellent adhesion of subsequent coating layers to olefinic substrates like TPO and superior properties as compared to previously used adhesion promoters containing chlorinated polyolefins.Type: GrantFiled: July 17, 2001Date of Patent: January 11, 2005Assignee: BASF CorporationInventors: John D.

Patent number: 6841700Abstract: The invention relates to a process for obtaining anhydrous or substantially anhydrous formic acid, in which firstly aqueous formic acid is produced by hydrolysis of methyl formate, with the methanol content in the methyl formate having been reduced in advance. The process according to the invention has the special feature that—before the hydrolysis of the methyl formate—the methanol content of the methanol-containing methyl formate is reduced in a distillation column, this distillation column simultaneously being employed for other separation functions during work-up of the formic acid.Type: GrantFiled: January 12, 2001Date of Patent: January 11, 2005Assignee: BASF AktiengesellschaftInventors: Heinz Auer, Bernd Bessling, Hans Hammer, Hans Hasse, Friedrich Sauer, Maximilian Vicari, Till Adrian
