摘要:
A column packing material comprising a porous support coated with a silicone polymer having an Si--R bond, wherein R is a hydrocarbon group having 1 to 18 carbon atoms, and an Si--R' bond, wherein R' is a hydrophilic group having one or more of polyoxyalkylene group or hydroxyl group at the terminal end, of which column packing material is produced by:modifying a porous support by bonding hydrocarbon groups to the porous support;eliminating a part of the hydrocarbon groups from the modified porous support; andmodifying the porous support by bonding hydrophilic groups thereto.
摘要:
A method for surface modification of a material by means of introducing the phosphorylcholine group represented by the following formula (1-1) onto the surface of the material by treating a material having amino groups with a chemical compound containing an aldehyde derivative obtained by the oxidative ring-opening reaction of glycerophosphorylcholine. The method of the present invention provides various materials such as medical materials having superior biocompatibility and hydrophilicity.
