New polymer brushes with multiple silicon containing functional end-groups for substrate modification for directed self-assembly applications

Abstract

This invention describes a polymer of structure (I) prepared by anionic polymerization, having a polydispersity of 1.00 to 1.05, wherein A is a styrene polymer segment selected from structure (A-1) or structure (A-2), wherein m is the number of styrene repeating units, and n is the number of styrene repeating units functionalized by a portion X, wherein m is an integer in the range of 5 to 200, and n is an integer in the range of 2 to 4, and wherein the portion X has structure (X-1) or (X-2). Described is a polymer of structure (I), prepared by anionic polymerization which has a polydispersity of 1.00 to 1.05, where A is styrenic polymeric segment selected from structure (A-1) or structure (A-2), where m is the number of styrene repeat units and n is the number of styrene repeat unit functionalized by the moiety X, where m is an integer ranging from 5 to 200, and n is an integer ranging from 2 to 4 and where the moiety X either has structure (X-1) or (X-2).
