Summary 2,4-Di-(2'-vinyloxyethoxy)benzylidenemalononitrile (2a), methyl 2,4-di-(2'-vinyloxyethoxy)benzylidenecyanoacetate (2b), 3,4-di-(2'-vinyloxyethoxy)benzylidenemalononitrile (4a), and methyl 3,4-di-(2'-vinyloxyethoxy)benzylidenecyanoacetate (4b) were prepared by the condensation of 2,4-di-(2'-vinyloxyethoxy)benzaldehyde (1) and 3,4-di-(2'-vinyloxyethoxy)benzaldehyde (3) with malononitrile or methyl cyanoacetate, respectively. Trifunctional vinyl ether monomers 2 and 4 were polymerized readily by free radical initiators to give optically transparent swelling poly(vinylethers) 5 and 6. Polymers 5 and 6 were not soluble in common organic solvents such as acetone and DMSO due to crosslinking. Polymers 5 and 6 showed a thermal stability up to 300°C in DSC thermograms.
