Surface modification of polymer substrate of any shape

摘要

Modification of the surface of polymer substrates by photochemically induced graft polymerisation comprises (1) pretreating the substrate with a photoinitiator (I) and aliphatically unsaturated monomer(s) (II); and (2) polymerising (II) on the pretreated substrate induced by electromagnetic radiation. Preferably the substrate consists of a polyamide, polyurethane, polyether block amide, polyester-amide or -imide, polyvinyl chloride (PVC), polysiloxane, polymethacrylate or polyterephthalate
