| titleOfInvention | Production of furan polymer |
| abstract | PURPOSE: To produce an org. solvent-soluble high-MW furan polymer without using any catalyst safely and easily, by reacting a specific furan compd. with a specific alkali metal compd. in an org. solvent in the absence of water and then in an O 2 atmosphere. n CONSTITUTION: A furan compd. of formula I (wherein R is H, alkyl, phenyl or alkyl-substd. phenyl; each of X 1 and X 2 is H or halogen) (e.g., furan, 3- methylfuran etc.) is reacted with an alkali metal compd. of formula II(wherein R 1 is alkyl, phenyl or alkyl-substd. phenyl; M is an alkali metal) (e.g., n- butyllithium, sec-butyllithium etc.) in an org. solvent and substantially in the absence of water and then in an O 2 atmosphere to give a furan polymer. By this method a high-MW furan polymer is safely and easily obtd. without using any catalyst. n COPYRIGHT: (C)1990,JPO&Japio |
