More Information
Summary:One aspect of this invention is a novel functional polymer having a polydispersity from 1 to about 1.12 comprising at least one reactive moiety, selected from a moiety comprising at least one N-coordinative functional group having at least one lone pair of electrons, a moiety comprising a dialkylsilyl group, or a mixture of both groups, wherein said reactive moiety is present in said functional styrenic polymer either on a repeat unit, on an end group or on both, and said N-coordinative functional group is either a monodentate N-coordinative functional group, a polydendate N-coordinative group or a mixture of thereof, and said monodentate N-coordinative functional group is an azide moiety (-N3) or a cyano moiety (-CN). Another aspect of this invention is the use of these novel polymer to selectively deposit a DSA directing layer on a metallic substrate.
