Abstract: A surface-modified blade rubber includes a surface modified by being subjected to irradiation treatment that generates radical active sites in the blade rubber and polymerization for graft polymerization starting from a generated radical active site. A method for modifying a blade rubber surface includes subjecting rubber of a blade rubber to irradiation treatment that generates radical active sites and polymerization for graft polymerization starting from a generated radical active site.

Abstract: A rubber product for wiping, a rubber for a wiper blade, a method for producing a rubber for a wiper blade, and a wiper unit. The rubber product for wiping, for example, includes a hydrophilic gel-like surface treatment layer coated on at least a wiping surface of the rubber product, wherein the wiping surface is softer due to water absorption when moistened than when dried.

Abstract: A collector is disclosed that is made of a polyolefin fiber having amidoxime groups and that is capable of efficient adsorptive recovery of useful metals such as uranium, vanadium, cobalt and titanium which are dissolved in small quantities in seawater. In the presence of a polymerizable monomer having a hydrophilic group, a polymerizable monomer having a cyano group is grafted to a polyolefin fiber by radiation-initiated graft polymerization to form both a hydrophilic group and a cyano group in the same graft side chains, and the cyano groups in the graft side chains are reacted with hydroxylamine to be converted to amidoxime groups, thereby producing a collector capable of recovering dissolved metals from seawater.

Abstract: An object of the present invention is to provide a structure of a metal collecting material for use in seawater or river water or industrial wastewater to give the most excellent adsorption efficiency. Another object of the present invention is to provide a process for efficiently separating and recovering valuable metals or noxious metals from a metal collecting material having collected said valuable metals from seawater or noxious metals from river water or wastewater with the least possible waste generation. A metal collector according to an aspect of the present invention is formed by stacking at least partially alternate layers of a fibrous metal collecting material with a spacer for introducing a liquid to be treated into said collecting material, wherein the area of spacer side faces represents 25-75% of the total area of collecting material side faces and spacer side faces in the side faces of the stack.
