Abstract
In order to modify the crosslinking of polyphenylene prepolymers, obtained by copolycondensation of di- and monoacetyl aromatic compounds or their ketals, the residual acetyl end groups were replaced by cyanomethylcinnamate or dicyanopropylidene groups, of the general formula −C(CH 3)=C(CN)R (where R=CN or COOC 2H 5). This was achieved by reacting the prepolymers with ethyl cyanoacetate or malonodinitrile. The structure of the resulting polymers was confirmed by IR-spectroscopic and elementary analysis. The ability of ethyl 2-cyano-3-methylcinnamate, taken as a model of the prepolymer end groups, to polymerize through the CN group or the substituted double bond, was examined.
