| titleOfInvention | Process for the preparation of heterocyclic styryl compounds and reaction products |
| abstract | Heterocyclic compounds having the formula n nwhere R is hydrogen, methyl or ethyl nR₁ independently in each occurrence is hydrogen alkyl ngroup of 1-4 carbons, and C(R):CH-Q nn is a number having an average value from 0 to 5 nQ has the formula n nZ is = 0, = S, or = N-R₂ nR is selected from hydrogen, alkyl, aryl, alkaryl, and aralkyl n nis a monocyclic or bicyclic heterocyclic ring selected from the ngroup consisting of pyridine, pyrazine, pyridazine, pyrimindine, quinoline isoquinoline, quinoxaline, quinazoline and nphthalazine nx is 1 to 3 nwith the proviso that when n is zero, the heterocyclic ring has nat least two -C(R):CH-Q groups nare prepared by condensing nitrogen heterocyclic comnpounds such as trimethyl pyridine with dialdehyde and nheterocyclic aldehydes such as furfural. These can be further nreacted and chain extended with bismaleimides or polynmaleimides. The compounds and their reaction products are nuseful to make heat resistant composites with various fibers nsuch as graphite fibers. |
