Abstract:
Disclosed is a method of preparing a modified halogenated polymer surface, comprising the steps of (a) activating the surface by modification with a polymerisation initiator by (a 1 ) reacting the halogenated polymer surface with sodium azide and subsequent (a 2 ) 1,3 dipolar cycloaddition with an alkine-functionalized initiator; or (a 3 ) reacting the halogenated polymer surface with mercapto-functionalized initiators; and (b) reacting the activated surface obtained in steps (a 1 )/(a 2 ) or (a 3 ) with polymerizable monomeric units A and/or B. The modified halogenated polymer substrates according to the invention exhibit outstanding properties.
