Abstract
The present invention provides new polymer compositions which contain novel substituted pyrazines or pyrazine derivatives ("NPD") which are functional and have useful application as a monomer (co-monomer) for a variety of high performance polymers such as polyester, polyarylate, polycarbonate, polyetherketones, epoxides, polyimides, polyamides, and polyamides-imides. These NPD have the general formula: ##STR1## wherein R.sub.1, R.sub.2, R.sub.3, and R.sub.4 are defined herein.
Claims37
A composition comprising (a) a polymer selected from the group consisting essentially of polycarbonate, polysulfone, polyester, polyarylate, polyetherketone, epoxide, polyimide, polyamide, and polyurethane, (b) having incorporated therein at least one monomer having the formula:
- ##STR23## wherein R.sub.1, R.sub.2, R.sub.3, and R.sub.4 are each independently selected from the group consisting of:
- ##STR24## wherein R.sub.5, R.sub.6, R.sub.7, R.sub.8, and R.sub.9 are each independently selected from the group consisting of:
- (1) SO.sub.3 NA
- (2) SO.sub.3 H
- (3) Cl
- (4) Br
- (5) F
- (6) OH
- (7) H ##STR25## where R.sub.10 is alkyl C.sub.1 to C.sub.10, phenyl, and --CH.sub.2 .dbd.CH.sub.2 ##STR26## where n is 1 to 100, R.sub.11 is alkyl C.sub.1 to C.sub.10 ##STR27## where R.sub.12 is alkyl C.sub.1 to C.sub.10 and phenyl ##STR28## where R.sub.13 is SO.sub.3 Na or NO.sub.2 ##STR29## where n is 1 to 100 ##STR30## (c) alkyl C.sub.1 to C.sub.10 (d) H
- (e) OH;
- and
- (f) Cl, Br, or F
- (g) NH.sub.2
- with the proviso that (1) at least one of R.sub.1, R.sub.2, R.sub.3, and R.sub.4 must be (a) or (b) above;
- (2) when one or two of R.sub.1, R.sub.2, R.sub.3, and R.sub.4 are (a) above and R.sub.5, R.sub.6, R.sub.7, R.sub.8, and R.sub.9 are H, the remaining two or three groups of R.sub.1, R.sub.2, R.sub.3, or R.sub.4 are not OH, Cl, and alkyl C.sub.1 to C.sub.10.
