METHOD FOR PRODUCING A HYDROPHILIC SURFACE ON PS/DVB COPOLYMER PARTICLES
A method for modifying a polymer carrier material for use as a stationary phase in an analytical or preparative separating method, the method comprising the steps of: providing a polymer carrier material, which is at least partly formed of aromatic hydrocarbon compounds comprising at least two vinyl or allyl substituents; producing hydroxy groups on/in the polymer carrier material by a method comprising an oxidative treatment of the polymer carrier material and a subsequent reductive or hydrolytic treatment of the reaction product; reacting the product from the previous step with a polyfunctional compound. The invention also relates to a polymer carrier material for use as a stationary phase in an analytical or preparative separating method, in particular a chromatography method, produced according to a method according to the invention.

ORGANIC SOLVENT TREATMENT METHOD
An organic solvent treatment method for removing particulates from an organic solvent used in a manufacturing step of electronic components is characterized by comprising a step of bringing the organic solvent into contact with a treatment material that has a positive or negative electric charge in water and has a moisture content of 3% by mass or more. An organic solvent treatment material, which is to be used in the manufacturing step of electronic components and which is for removing particulates from an organic solvent by coming into contact with the organic solvent used in the manufacturing step of electronic components, has a positive or negative electric charge in water.

Corrosion inhibitor
The present invention relates to a corrosion inhibitor and inhibitor provided within a coating material for coating a metal, particularly but not exclusively steel. The corrosion inhibitor in a coating particularly protects a sacrificial coating such as zinc or zinc alloy on galvanised steel which in turn therefore provides improved corrosion resistance to the underlying steel. According to an aspect of the invention there is a corrosion inhibitor provided in a polymer binder, the corrosion inhibitor comprising an organic ion in an ion exchange resin.
