Abstract: A method for the improvement of yield and freeness which does not discolor the paper product and gives a long life to the product and exerts stable yield improving effect even for the paper stuff containing much deinked pulp and filler as well as a yield improving promotor used in this method are provided.In the method for the improvement of yield and freeness in the paper-making process and the waste water treating process according to the present invention, a special phenol resin is used in combination with polyethylene oxide (PEO). The phenol resin of the present invention is a sulfonated phenol-formaldehyde resin synthesized by sulfonating a phenol and then condensing it with formaldehyde. Preferred as the phenol to be sulfonated are Bisphenol A and Bisphenol S.By using the method of the present invention, the yields of fine fiber and filler can be improved and the paper stuffs can be saved and the waste water treating load can be decreased.

Abstract: A resin composition having excellent antistatic properties is provided which comprises (A) 100 parts by weight of a styrene resin, (B) 3 to 35 parts by weight of a polyethylene oxide, (C) 0.1 to 10 parts by weight of a styrene-acrylonitrile-hydroxyalkyl acrylate copolymer and/or a styrene-acrylonitrile-hydroxyalkyl methacrylate copolymer, (D) 4 to 100 parts by weight of a (meth)acrylic ester polymer, and/or an oxide selected from the group consisting of titanium oxide, zinc oxide and magnesium oxide, the oxide being present in an amount of 0.7 to 5 parts by weight per 100 parts by weight of the combined amount of components (A) and (B), and (E) a surface-active agent comprising a specified sulfonic acid salt or alkylsulfuric acid salt, the surface-active agent being present in an amount of 0.4 to 5 parts by weight per 100 parts by weight of the combined amount of components (A), (B), (C) and (D). This resin composition can be used for general household articles including, for example, wardrobe cases.

Abstract: A coated optical fiber comprising an optical fiber for transmitting information having coated thereon a ring-opened (co)polymer of a norbornene derivative having a polar group. Due to the excellent moldability of the polymer, the coated optical fiber can be produced with high productivity. Even when the coated optical fiber is produced at high speeds, the molding strain on the coating is small, and the coated optical fiber has a reduced heat shrinkage.
