1. A block copolymer formulation, comprising:
a block copolymer blend, comprising:
a first poly(acylate)-b-poly(silyl acrylate) block copolymer (“DB1”) having a DB1 poly(acrylate) block, a DB1 poly(silyl acrylate) block and a DB1 number average molecular weight, MN-DB1, of 10 to 1,000 kg/mol; a DB1 polydispersity, PDDB1, of 1 to 3; and,a second poly(acrylate)-b-poly(silyl acrylate) block copolymer (“DB2”) having a DB2 poly(acrylate) block, a DB2 poly(silyl acrylate) block and a DB2 number average molecular weight, MN-DB2, of 1 to 1,000 kg/mol; a DB2 polydispersity, PDDB2, of 1 to 3; and, ≧2 wt % antioxidant (based on the weight of the block copolymer blend).
