摘要: A trifluoroacetic acid-based etchant is described that can remove a sacrificial component of a multi-component polymer, e.g., a self-assembled block copolymer. The etchant can operate at a high etch rate and with excellent selectivity. The etchant can remove a hydrolysable sacrificial component such as a polylactide block from a self-assembled block copolymer. The etchant enables the macroscopic preservation of the nanostructure morphologies of self-assembled copolymers (e.g., poly(styrene-block-lactide) copolymers) and can yield pristine porous films of the non-hydrolysable component of the starting multi-component polymer.

摘要: The present invention is related to novel preparative methods to a novel class of polymer network materials with a highly branched poly(glycidyl ether) (PGE) structure. Said polymer networks are prepared by a simple procedure involving ring-opening polymerisation and the method is applicable to a wide range of glycidyl ether containing monomers. The method comprises the step of copolymerising (A) at least one multi-topic glycidyl ether comprising at least three glycidyl ether groups with (B) at least one glycidyl ether component comprising at least one glycidyl ether group by ring opening polymerisation, wherein the multi-topic glycidyl ether (A) is glycerol glycidyl ether (GGE) having the Formula (I) and the glycidyl ether component (B) is selected from monoglycidyl ethers comprising one glycidyl ether group and diglycidyl ethers comprising two glycidyl ether groups.
