Abstract

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.
