Abstract
A diblock copolymer system that self-assembles at very low molecular weights to form very small features is described. One polymer in the block copolymer contains silicon, and the other polymer is a polylactide. The block copolymer may be synthesized by a combination of anionic and ring opening polymerization reactions. This block copolymer may form nanoporous materials that can be used as etch masks in lithographic patterning.
